|Caster sugar||6 Ounce|
|Lemons||2 (use rind and juice)|
Put butter, sugar, lemon juice and very finely grated rind into a basin, and stand this over a pan of boiling water.
Blend all together, and when butter has melted, add the eggs, well whisked, to the other ingredients.
Stir until mixture thickens, which will take about 20 minutes.
Pour into warmed jars and cover when cold.
