Aspic Jelly From French Gelatine

Ingredients

Directions

Prepare the stock

  1. Chop the calves' feet into eight pieces and wash them in cold water.

  2. Place the feet in a stewpan with enough cold water to cover them and bring to a boil.

  3. Pour off the water, wash the feet again, and return them to the cleaned stewpan with 2 quarts of water. Bring to a boil.

  4. Skim occasionally. Add ½ teaspoon salt.

  5. Add the other ingredients except lemon, eggs, and vinegars. Let it boil gently for 5 hours.

  6. Strain through a fine sieve into a basin. Let it cool.

  7. Remove the fat. Wipe the top of the stock with a cloth dipped in hot water.

Clarify and season

  1. Return the stock to a clean stewpan.

  2. Add lemon peel and juice.

  3. Add whipped egg whites and shells.

  4. Add vinegars.

  5. Add salt to taste.

  6. Whisk over heat until boiling.

  7. Let it stand off the heat for 30 minutes to form a crust.

  8. Pour the contents through a clean soup cloth into a basin.

  9. Allow it to pass through slowly a second time.

Mold and serve

  1. Scald a mold with boiling water. Rinse with cold water.

  2. Garnish with fish or vegetables.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Calves' feet
Release gelatin into the stock, which sets the jelly when cooled.
Egg whites
Collect impurities as they cook, clarifying the stock into a clear jelly.
Lemon juice
Adds acidity that brightens the flavour and helps the jelly taste clean.
Sherry
Adds aroma and depth of flavour to the stock.
Malt vinegar
Adds acidity and sharp flavour to the finished jelly.

The step that matters

Clarifying with egg whites. Whisking the stock until boiling lets the egg whites bind impurities into a crust. Boiling too hard or skipping the slow second straining leaves the jelly cloudy.

Swap the lemon

How well each one fits the dish's main ingredients (egg, sherry, malt, vinegar, tarragon):

  4. Applefits about as well

Fit is the average pairing score against egg, sherry, malt, vinegar, tarragon. Candidates are from the same food group and used in at least 100 recipes.
