Puka Henry's Lime Curd

Ingredients:
4 large eggs
2 egg yolks
150 g sugar
150 g margarine or butter.
150 mL Darwin Limes ( 6 large limes).  Grate the zest of 4 limes.
Zest of 2 lemons

Method:
Put water into a saucepan and heat until simmering.   Beat the eggs and yolks in a jug and pour into a glass bowl.   Add margarine, sugar, lime juice and the lime and lemon zest.   Put the bowl onto the saucepan and stir until sugar dissolves and margarine melts.    Cook stirring from time to time; no need to stir continously as the curd thickens.   The curd is ready when it is thick enough to be able to draw a line through it on the back of the wooden spoon.   Pour into sterilized jars and cover with lids.    When cool place in the fridge.
