Vietnamese Crab and Asparagus Soup (Sup Mang Cua)

Apparently Vietnamese crab and asparagus soup (súp măng cua) is a popular soup eaten on special occasions such as wedding banquets in Vietnam. My parents grew up eating this soup (in Vietnam). My father remembers his older brother, a self-trained chef who owned a catering business would make this delicious soup for weddings and other ceremonial events. Fresh asparagus was not available so he made it using canned ones imported from Taiwan. My father said the asparagus became thin strands when cooked. My mother said her family would make this soup also using canned asparagus. I don't remember ever eating this soup as a child in Vietnam. Perhaps during the war people lacked access to these luxury items. Over the last several decades I have traveled to Vietnam countless times, attended many special events and ate in restaurants all over the country I don't recall eating this soup or seeing it on a menu. Once in Da Lat I was delighted to find a vendor selling fresh but very tall thin asparagus in a market. I bought some to cook for my grandmother. I was disappointed to find that they were tough and inedible.

During the beginning of the pandemic I started a small garden. It wasn't intentionally planned but it turned out to be quite therapeutic, educational and kept me busy during the spring and summer months. In the spring of 2021 my father came and helped me plant asparagus roots, other vegetables and berries. The following spring I planted more asparagus roots and seeds. As some of you may know they take about 2-3 years before they can be harvested. Finally this spring I am able to pick some. Freshly harvested asparagus are delicious--tender and sweet.

In this simple recipe you may use as much asparagus and crab meat as you prefer. My mother picked the scrumptious crab meat from 4 large fresh caught Maine Jonah crabs. If you are not very skilled at picking crab meat you may certainly purchase from a can or already picked meat from a fish market. Some people cut the asparagus in 1/2 to 1 inch pieces. I prefer to slice mine as thinly as possible on a bias. I like to place my whisked egg in a small bag, cut a tiny hole in one corner and while stirring the pot I drizzle the egg in the pot. This will create elongated wispy strands. If you prefer the soup to be thicker then add more cornstarch or tapioca. Be sure to mix it with cool or cold water before you add it to the pot. The Vietnamese people generally make this soup using chicken or pork broth, but not me. I am trying to make a dent in the population of the highly invasive green crabs! I seasoned my soup only with fish sauce. Feel free to garnish with fresh chopped scallions, chopped cilantro and white or black pepper.

Leek and Green Crab Soup

leek and green crab soup
 

I love eating leek and potato soup. However, this is without the potato and it is equally tasty. If this soup is too thick then add extra stock.

Leek and Green Crab Soup

Ingredients:

4 leeks, halved lengthwise, sliced thinly, washed and drained
About 2 Tbsp olive oil
About 2 Tbsp of butter (salted or unsalted)
1 C heavy cream or half and half
About 1 1/2 to 2 tsp sea salt
 
Method:
 
Saute the leek in oil and butter over medium high heat until the leek is tender and soft, about 10-15 minutes. Puree the leek and broth. Heat the mixture in a pot and add cream, season with salt. Whisk well to mix and serve hot. May serve with a drizzle of extra cream if interested.

Leek, Potato, and Green Crab Soup

Recently Dr. Becca Selden, from the Department of Biological Sciences at Wellesley College in Massachusetts invited me for a green crab cooking demo. I made 2 simple soups and both were well received by those who attended. I am glad I left the campus with empty pots! One of them is this leek, potato, and green crab soup using half green crab stock and half chicken stock. I don't like to waste food so if the leek has some greens on it I usually use it for extra fiber and color. If you prefer a thicker soup then decrease the amount of stock use to blend and gradually add more to the consistency you like. It's easier to thin it later. You certainly can make this using all green crab stock.

Leek, Potato, and Green Crab Soup

Ingredients: 

1 large leek or 2 small, cut lengthwise, sliced, washed and drained
1 Tbsp olive oil
1 Tbsp butter (salted or unsalted)
2 large potatoes, peeled and cubed
2 C chicken stock
1 C heavy cream or half and half
About 1 to 1 1/2 tsp salt 

Method:

Saute leek in oil and butter over medium high heat until the leek is tender and soft, about 10-15 minutes. Boil the potato in chicken broth until fork tender. Puree leek, potato, chicken broth, and crab stock to the smoothness that you prefer. Add cream, season with salt, and cook at medium low heat until everything is heated through. Whisk to blend. May garnish with a drizzle of cream, a pinch of ground black or white pepper, chopped chives, or anything you prefer.

Basic Green Crab Stock

basic green crab stock

I have posted a few green crab stocks with ingredients besides green crabs and water. This particular basic stock is made with just 2 ingredients, green crabs and water. When I make my stock I avoid adding salt unless I plan on using it immediately. You can make any stock as concentrated as you prefer. If you make a concentrated stock then you will need less water, which to me means less storage space in the refrigerator or freezer. In general my green crabs to water ratio is about 15 crabs for 2-6 cups of water. These green crabs vary in size so my water will depend on this and how concentrate I prefer. Don't be afraid to experiment. Most of the time I clean the crabs, crush them and add water. I don't focus on any particular crab to water ratio and I hope you don't either. You may also check out these posts: How to Process Green Crabs Humanely, How to Prepare Green Crabs for Making Stock, Simple Green Crab Stock, and Green Crab Stock For Chowders.

Basic Green Crab Stock 

Ingredients:

Crabs
Water

Method:  

Remove the carapace, gills, apron and mouth from each crab. Wash well in cold to remove all the mud and sand. Crush the crabs, put them in a large pot and add water. Boil gently and stir occasionally for about 25-30 minutes. Strain right away or let it cool and strain. Before using may add more water if the stock is too concentrated for your taste. May compost the shells.

 

Butternut Squash and Green Crab Soup

butternut squash and green crab soup

It has been a long time since I posted anything on this blog. I am still working full-time as a family nurse practitioner at the clinic seeing patients. Despite the long hours I managed to stay healthy perhaps due to eating a copious amount of green crabs! 😃

Recently Dr. Becca Selden, from the Department of Biological Sciences at Wellesley College in Massachusetts invited me for a green crab cooking demo. I made 2 simple soups for the students and faculty to try. I was pleased and impressed to see so many students excited about eating green crabs! One of the soups was a butternut squash and green crab soup. I made it using coconut milk instead of dairy in case anyone was lactose intolerant. Luckily no one there had any food allergy or issues which made me very happy.

Butternut Squash and Green Crab Soup

Ingredients:
 
1 butternut squash (about 2 1/2 to 3 lbs)
Olive oil 
1 head of garlic
1 small white or yellow onion
3 1/2 to 4 C Basic Green Crab Stock (see recipe below)
1 C coconut milk
About 1/2 tsp salt to taste
About 1/2 tsp white or black pepper to taste
Coconut Drizzle (see recipe below) 

Method:

Peel and cut the butternut squash in half. Remove and discard the seeds. Slice the squash about 1/2 inch thick. Line in a single layer on a cookie sheet and drizzle with a little olive oil. Wrap the whole garlic in foil (may drizzle with oil if interested). Roast the squash and garlic in a preheated oven at 400 degrees F until the squash is fork tender, about 25-30 minutes. May broil for the last 5-10 minutes if interested. Peel and dice the onion. Saute the onion in a little olive oil until translucent and soft. Puree the roasted butternut squash, roasted garlic, sauteed onion, broth and coconut milk. Heat the pureed mixture until hot. Season with salt and pepper to taste. Whisk well to blend and serve hot with some coconut drizzle (see recipe below).

 

Coconut Drizzle

Ingredients:
 
Approximately 1 Tbsp of cornstarch 
Approximately 1 Tbsp water 
1/2 C coconut milk
Pinch of salt

Method: 

Mix the cornstarch and water until well blended. Cook this with coconut milk and salt. Whisk to blend. Drizzle over the butternut squash and green crab soup to garnish.

How to Compost Green Crabs

How to Compost Green Crabs

Every time I hear someone compost perfectly edible items I cringe because I don't like to see, hear, or read about wasted food. I believe in consuming what you can first and only compost what is inedible after. This same concept goes for the invasive green crabs. Just like anything, there are many different methods to compost matters but this short post is about how I compost green crabs. After returning home from the dock with a bucket of crabs I would spend some time preparing them by removing the carapace, apron, gills, and mouthparts to discard. Please check out How to Prepare Hard-Shell Green Crabs post for further details and tutorials. I save the bodies and roe separately for cooking. The discarded parts would be boiled for about 5 minutes, just long enough to cook them. The reason I devote in this extra 5-minute step is to decrease the stench of decaying shellfish and to prevent attracting animals and insects to my outdoor compost container. I would empty the cooked discarded parts and liquid in my home-made recycled compost receptacle--made from an old wooden cabinet minus the back and a door. It lies open to the ground and the top covers with a wire mesh nailed to a wooden frame heavy enough to prevent it from blowing away or having it knocked over by most animals. I say most because we do have an occasional bear visiting in the area (New Hampshire). One of our neighbors is known to have frequent conversations with bears! My husband saw a black bear recently while driving so they are definitely around!

Do add a little soil to the container for the worms to be happy. These worms are usually well fed and large, great for fishing bait! And about once or twice a month turn the organic material inside in order for the items to break down more evenly.

Sauteed Cabbage, Tomato and Stinging Nettle

I normally make this dish with just cabbage, tomato, meat, and water or chicken stock. This time I added a large handful of stinging nettles that I harvested for extra nutrients, texture, and color. Use however many tomatoes you prefer. I love fresh tomatoes so I used 3 medium-sized ones. You may use ground or thin slices of meat such as pork, turkey, or chicken for this dish. You may use either stock from dried crabs or fresh crabs.

Be sure to harvest stinging nettle with gloves and proper harvesting clothing (i.e., pants, socks, closed shoes, long-sleeved shirt, and etc.) as they do sting! Please eat only wild plants that you can positively identify. If you have any health problems or are taking any medicines (prescription, over-the-counter or herbal supplement) please consult with your health care providers before eating any wild edible plants.

Here are a few links on stinging nettle.

Stinging Nettle Potato Soup

Recently I discovered stinging nettle growing wildly here in New Hampshire. I have heard about these nutritious plants but I have never encountered them in the wilderness. Be sure to harvest them with gloves and proper harvesting clothing (i.e., pants, socks, closed shoes, long-sleeved shirt, and etc.) as they do sting! Please eat only wild plants that you can positivity identify. If you have any health problems or are taking any medicines (prescription, over-the-counter or herbal supplement) please consult with your health care providers before eating any wild edible plants.

You can drizzle a little cream or coconut milk to this soup if interested. If you do not have or prefer not to use fish sauce then just add more salt or chicken bouillon to season this soup. For this recipe, I double my Basic Rehydrated Green Crab Stock. For a faster way to cook potato, slice it as thinly as possible.

Method:

Make the crab broth, strain, and reserve the broth. In a medium-sized pot add the potato and cook until soft, drain the liquid. Add the crab broth and stinging nettle tips to the cooked potato, cook for 2-3 minutes. Season with salt and fish sauce. Turn off heat and let everything slightly cool before pureeing or blending everything. Garnish with chive flowers and chopped leaves.

Basic Rehydrated Green Crab Stock

This basic green crab stock or broth is made from dried green crabs. Increase or decrease the ratio of ingredients to make more or less stock. You may add more crabs if you prefer a more concentrated broth. Before adding the dried crabs in the water you may crush them further using a mortar and pestle or a rolling pin to extract the most flavor out of them. This stock is very basic. You may add extra ingredients such as dried squid, dried shrimp, bonito flakes, animal or fish bones, seaweed, mushrooms, onion, scallions, ginger, cilantro stems/roots, carrots, parsnip, daikon, and celery for more flavors. I generally do not season my stock or broth as I will add it later in the final stage of cooking. My seasoning includes one or several of these ingredients; salt, fish sauce, soy sauce, fresh or dried beef, chicken, or mushroom stock.
