Mock-Turtle Bean Soup

Ingredients

• 1 quart French mock-turtle soup beans (or kidney or rice beans)
• 1 quart soft lukewarm water
• 1 gallon cold water
• 2 lb salt pork
• 1 celery head, shredded
• to taste pepper (cayenne preferred)
• for serving lemon slices

Method

Soak the beans overnight in soft lukewarm water. This hydration shortens cooking time and opens the skin enough that the beans won't split, keeping the broth clear rather than cloudy. The next morning, drain them and start fresh with cold water — this removes the fermentation compounds that cause digestive upset.

Place the drained beans in a heavy pot with 1 gallon of cold water and the salt pork in a single piece. Bring to a rolling boil, then reduce to a simmer. The salt pork will render its fat into the broth and season it throughout; the collagen in the meat toughens if you boil violently, so keep the heat low enough that only occasional bubbles break the surface. Cover the pot and leave it undisturbed for 3 hours. The beans will soften completely, their starches thickening the liquid into a proper soup. You're looking for beans that collapse between your tongue and the roof of your mouth, not ones that hold their shape.

After 3 hours, add the shredded celery and cayenne pepper to taste. Simmer uncovered for another 30 minutes so the celery softens and its flavour integrates into the slow-cooking broth. The uncovered pot also allows steam to escape; you want a slightly reduced, more concentrated broth at this stage.

Pull the salt pork from the pot and set it aside — it has given everything it has to give. Pass the entire contents through a fine sieve or mouli, pressing the beans hard against the mesh with the back of a wooden spoon. This forces the soft bean flesh through, thickening the liquid into a velvety purée whilst the skins and any fibrous celery remain behind. The result should coat the back of a spoon.

Return the purée to the pot, taste, and adjust the seasoning. Serve hot in wide bowls with a thin slice of fresh lemon balanced on the rim. The acidity cuts the richness of the pork fat and lifts the earthy bean flavour — this is not optional, not a garnish. Pass additional lemon slices at the table for guests to adjust to their preference.
