Punch Jelly

Ingredients

Directions

Make the jelly

  1. In a saucepan, combine all ingredients except the whisky.

  2. Cut the yellow part of the lemon rinds as finely as possible.

  3. Stir the mixture until it boils, then cover and let it stand for 10 minutes.

  4. Pass through a jelly bag with 1 quart of boiling water.

Layer the mold

  1. Add the jelly and slightly warmed whisky.

  2. Pour 1 inch of jelly into a mold and let it nearly set.

  3. Garnish with small quarters of peeled and cut lemon.

  4. Continue layering with cold jelly and lemon until the mold is full.

Unmold

  1. Once firm, dip the mold in warm water and turn out quickly.

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

What each ingredient does

Irish whisky
Provides the main flavour and alcohol base of the jelly.
Leaf gelatine
Sets the liquid so the jelly holds its shape when turned out.
Egg whites and shells
Bind to impurities as they heat, clarifying the jelly to a clear look.
Lump sugar
Adds sweetness and balances the alcohol and lemon.
Lemon juice
Adds acidity that brightens the flavour of the jelly.

The step that matters

Let the layer nearly set before adding the next. If the layer is still too liquid, the new layer mixes into it and the stripes blur. If it is fully set, the layers will not bond and may separate when cut.

Swap the lemon

How well each one fits the dish's main ingredients (whisky, sugar, egg):

  1. Vanillafits better
  2. Applefits better
  3. Raisinfits better
  4. Lemonthe original

Fit is the average pairing score against whisky, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
