For the custard
1 rounded dsp of granulated sugar
2 rounded dsps of custard powder
3/4 pint of milk, full fat or semi skimmed.
Traditionally made in a saucepan on the hob, but I make mine in the microwave.
Place sugar and powder in jug and stir in a small amount of milk. When well mixed stir in remainder of milk. Microwave on high for 3-4 minutes, stirring halfway through. If making in a saucepan stir until it comes to the boil and has thicken.
