To make without a ThermoCook
Place all the ingredients in a double boiler or in a large heatproof bowl over a pan of simmering water. Sir until the sugar has dissolved and continue to heat gently, stirring, for about 20 minutes until thick enough to coat the back of the spoon; do not allow to boil or it will curdle.
Strain the lemon curd through a fine sieve. Pot and cover in the usual way. Store in the refrigerator and use within 2-3 weeks.
The same recipe can be used for Lemon Curd, replacing the oranges with lemons.
