Instructions

1. 1

   Prepare the turtle

   Thaw the turtle completely in the refrigerator. Set aside the reserved fat, then inspect the pieces and retain every clean bone, strip of skin, and piece of cartilage because they give the broth its body. The source applies Blanchings (No. 273) to the shell and flippers: with commercially dressed turtle, use that operation only on bloodied skin-on or cartilaginous pieces. Lower those pieces into boiling water for 5 minutes, drain, rinse under cold water, and scrape away any loose membrane. Clean flesh needs no soaking, which would send its flavor down the drain.

   Keep raw turtle and its utensils away from ready-to-eat food, just as you would raw poultry. Wash the board, knife, sink, and your hands thoroughly before continuing.
2. 2

   Begin the extraction

   Put the turtle flesh, bones, blanched connective pieces, consommé, cold water, and 1 tablespoon salt into a heavy stockpot. Bring the liquid slowly toward the first lazy bubbles, skimming the grey foam as it rises. Add the carrot, leek, celery, onion, shallots, parsley stalks, garlic, and whole clove. Lower the heat until the surface merely trembles, then cook partially covered for 2½ hours. If the pot boils hard and the broth clouds, stop the heat, add a cup of cold water, and let it settle for 10 minutes before skimming again. Continue more gently and strain twice later. Ça se rattrape.

3. 3

   Cut the garnish

   Begin checking the turtle after 2 hours. Lift out each piece as soon as its meat pulls cleanly from the bone, since different muscles soften at different moments. Reserve about 12 ounces (340 g) of the best tender meat, skin, and gelatinous connective tissue. Trim it carefully and cut it into ½-inch (1.25 cm) squares, the practical home-spoon equivalent of the original large service garnish. Cover and hold it in a little strained broth. Return the stripped bones and any still-firm cartilage to the stockpot.

4. 4

   Infuse turtle herbs

   Tie the basil, marjoram, sage, rosemary, savory, thyme, and lemon zest in a small square of muslin. Put the coriander seeds and peppercorns into a second spice bag so no stray seed reaches the bowl. Add both bags for the final hour of cooking, keeping the broth at the same bare tremble. This last infusion is the soup's unmistakable accent; longer cooking would make the sage and rosemary coarse and medicinal.

5. 5

   Poach the fat

   While the herbs infuse, bring the 2 cups water and 2 teaspoons salt to a gentle simmer in a small saucepan. Add the reserved turtle fat and poach without boiling until cooked through and tender, about 15 minutes; its center must reach at least 165°F (74°C). Let it cool in the liquid for 5 minutes, then slice it thinly. If it becomes too soft to cut, chill it briefly in its poaching liquid until firm. Do not color butter with herbs and call it green fat. The lawful freshwater garnish is different, and honesty tastes better.

6. 6

   Strain and measure

   Remove both herb bags. Pour the broth through a fine sieve lined with damp muslin into a clean pot, allowing it to drain without pressing the solids; pressure forces sediment through and muddies what you spent the evening clarifying by patience. Skim away heavy surface fat but leave a slight amber sheen. Measure the broth. If you have more than 2 quarts, reduce it gently to that volume; if you have less, add enough boiling water or hot consommé to restore 2 quarts. It should lightly coat the lips when tasted, not sit thick like sauce.

7. 7

   Finish with Madeira

   Return the diced turtle garnish and sliced reserved fat to the strained broth. Heat gently until everything is thoroughly hot, then taste and correct the salt. Take the pot off the heat and stir in the Madeira, preserving the source proportion of one small port glass for every quart. Do not boil after the wine goes in or its lifted, nutty perfume disappears. Ladle generously into warmed soup plates, giving each guest both tender turtle and gelatinous garnish. À table!

Chef Tips

• •Buy only inspected turtle from a lawful specialist who can identify the farm and species. Wild turtle may be protected, contaminated, or illegal to sell. Green sea turtle is not a sourcing challenge to overcome; it is outside this kitchen.
• •Ask for bone-in dressed freshwater turtle with skin, cartilage, and its natural fat included. That fat may be yellow or pale olive rather than the celebrated green fat of the London service. The substitution is not invisible, but it preserves the rich garnish without pretending a protected species is available.
• •The consommé must be unsalted and rich enough to gel when refrigerated. It replaces the carapace and plastron cooking liquor the original kitchen had at hand, so thin boxed broth leaves the soup without its proper body. Reduce a weak stock before measuring it for the recipe; never thicken this clear soup with roux.
• •Fresh savory can be difficult to find. A specialist herb grower is the first choice, but ½ teaspoon (2.5 ml / 0.5 g) dried savory can replace the four fresh sprigs. Do not omit the herb entirely, because it belongs to the turtle bouquet rather than serving as decoration.
• •Madeira enters after the heat is turned off. Taste the broth first, add the full measured quantity, and serve promptly. The wine should lift the long-cooked stock, not cook down into sweetness.

Advance Preparation

• •Order the turtle well ahead and confirm that the package includes bone, skin, cartilage, and natural fat. Thaw it on a tray in the refrigerator, never on the counter.
• •The broth can be prepared through straining up to 2 days ahead. Cool it promptly in shallow containers, refrigerate the diced garnish and poached fat separately, then reheat everything gently and add the Madeira only at service.
• •The strained broth freezes well for up to 2 months without the Madeira. It may set as firmly as jelly when cold; that is the proper sign of extracted gelatin, and it will liquefy again over gentle heat.
