Dungeness Crab Bisque

Today I attempted to make a consommé from a dungeness crab carcass, which turned out to be an interesting way to make crab stock. I started this recipe with the ingredient ratio from Williams-Sonoma, but found that the bisque was too watery and lacked depth. I later added the other ingredients in the Food Network's crab bisque recipe, minus the whole dungeness crabs which I did not have on hand and made a few adjustments. Also omitted was tarragon, which I neither have fresh nor dried in the pantry.

Using a 5-qt programmable crockpot, I cooked a dungeness crab carcass for the better part of the day; about 6 hours on the "high" setting, and 8 hours on the "low", though I don't think it really cooked for 14 hours. In the crockpot, I also added some Shaoxing red rice wine. Use a strainer to extract just the liquid from the crockpot into a pot large enough to accommodate it and the rest of the bisque ingredients. Unlike all other crab bisque recipes, this one extracts all the crab flavor from one carcass and the meat is from canned crab; though, you could use freshly cooked crab meat if it were in season. At the moment, it is not in season in the Pacific Northwest and live crab prices have gone back up to their off-season norm of about $5/lb. This yielded roughly 3 quarts of crab stock.

Also, note if the canned crab contains added salt. If it does, like the Trader Joe's canned crab, rinse it with water to remove the excess salty water, then strain it before adding to the bisque. This will help to control how much sodium actually gets into the soup.

Ingredients

crab stock (can also substitute chicken or fish stock)
Two 6 oz cans of crab meat
 2 c. heavy cream
1/2 c. sweet marsala wine
One 14.5 oz can of organic diced tomatoes (or 3 whole tomatoes)
2 tbsp organic tomato paste

2 tbsp olive oil
1 tbsp unsalted butter
2 celery stalks, trimmed and diced
1 carrot, diced
5 garlic cloves, minced
3 shallots, minced

1 bay leaf
cayenne pepper
freshly ground black pepper
Himalayan pink salt
pinch of ground thyme
juice of 1/2 a lemon

Directions

1. Prepare crab stock by simmering a crab carcass with some dry wine (rice wine works well) in a stockpot or crockpot for several hours. Strain to remove shell particulates and other non-liquid items into a clean stockpot.

2. In a small saute pan, melt olive oil and butter together, then add shallots, carrots, celery, and garlic. Cook over low heat until shallots become translucent. Add to crab stock.

If you have a limited number of cooking pots, you may find this reversed step more optimal for the kitchen instead of starting with these ingredients in the stockpot then adding the strained crab stock to deglaze the pot.

3. Add the heavy cream, bay leaf, marsala wine, lemon juice, and spices (cayenne pepper, thyme, pink salt, freshly ground black pepper. Season to taste.

4. Add the diced tomatoes and tomato paste. Stir the bisque so that the paste dissolves into the stock.

5. Let the stock come to a boil, then simmer for at least an hour. In the last half hour of cooking (before serving), add the canned crab or freshly cooked crab meat (cut into 1" pieces).

6. In batches, pureé in a food prep or blender. In this step, you can strain the bisque so that only the liquid remains, or serve it as is while still warm.
