Tangy Lemon Curd

Ingredients

Directions

Prepare

  1. Extract the juice of the lemons, and then grate the rind very thinly.

  2. Beat the eggs, and then put the eggs, lemon rind and lemon juice, butter and sugar into the top of a double boiler.

Make the curd

  1. Stir over simmering water until the mixture is glossy and thick enough to coat the back of a wooden spoon.

  2. Strain into sterilized jars and cover.

Store

  1. Unless you plan to use the lemon curd within a couple of days, refrain from making large quantities at a time.

  2. Store in a fridge.

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

What each ingredient does

Eggs
Set and thicken the curd as they cook, giving it body.
Sugar
Sweetens the curd and balances the sharpness of the lemon.
Butter
Adds fat for a smooth, rich texture and glossy finish.
Lemons
Provide the juice for acidity and the rind for aroma.

The step that matters

Stirring over simmering water. Egg proteins set gently when heated slowly; if the water is too hot or the mixture is heated too fast, the eggs can scramble and the curd turns grainy. Gentle, constant stirring keeps it smooth and thick.
