Jelly

Ingredients

Directions

Prepare the lemon

  1. Squeeze and strain the lemon juice.

Make the jelly

  1. In a clean enamelled pan, combine egg whites, shells, lemon peel, strained juice, cinnamon, cloves, and sugar, then whisk the mixture together.

  2. Add gelatine and hot water, whisking until it boils.

  3. Boil for 5 minutes, then remove from heat and let stand for 5 minutes.

Strain and set

  1. Prepare a jelly bag by pouring 2 quarts of boiling water through it.

  2. Place two basins under the jelly bag to strain the jelly.

  3. Pour the jelly into the bag, switching basins as needed until the jelly is clear.

  4. Pour the clear jelly into a tin jelly mould and set aside to cool.

  5. Once set, dip the mould in hot water to loosen the jelly and turn it out.

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

What each ingredient does

Eggs
Egg whites and shells collect cloudy particles as the mixture boils, clarifying the jelly.
Gelatine
Sets the hot liquid into a firm, sliceable jelly as it cools.
Lemon juice
Provides sharp acidity that balances the sweetness and brightens the flavour.
Sugar
Adds sweetness and body to the lemon liquid.
Cinnamon
Adds warm aromatic flavour to the jelly.

The step that matters

Boiling and standing before straining. Boiling the egg whites in the liquid makes them coagulate and trap cloudy particles, and standing lets them settle. Straining through the bag then gives a clear jelly, so the boil and rest must be completed before straining.
