Servings: 6
Prep Time2 minutes
Cook Time10 minutes
Total Time12 minutes

Ingredients

  • 4 eggs - 1
  • 300 ml double cream - 2
  • 150 ml milk - 3
  • 110 g sugar - 4
  • 1 tsp vanilla extract - 5

To thicken

  • 2 tsp cornflour - optional

Instructions

  • Add all the ingredients aside from the cornflour / cornstarch to the blender.
    4 eggs, 300 ml double cream, 150 ml milk, 110 g sugar, 1 tsp vanilla extract
  •  Switch the blender on and let it run on high for 5 minutes.
    Make sure that the central bung is set to vent so the steam can escape.
  • Check the consistency of custard once it starts to steam.
    If you want to make a thick spooning custard add the cornflour and blend for another minute and check again, then check every 30 seconds.
    Once the cornflour is added the custard will suddenly thicken.
    2 tsp cornflour
  • Once ready the custard will coat the back of a spoon. Remember that as it cools it will thicken some more.
  • Transfer to a jug and serve immediately

Notes

Ingredient notes 
1 - eggs - medium or large.  Yes we are using whole eggs with the whites. This is a power blender. There will not be any trace of lumps of egg white.
2 - double cream that is is at least 40% fat. If using heavy cream then substitute extra heavy cream for the milk. 
3 - Any milk will do here.  I usually use semi skimmed 
4 - sugar - I generally use golden caster for ease of use and flavour. A darker sugar will give a darker custard with a more intense flavour. 
5 - vanilla - use a good quality extract or paste which is natural vanilla. Avoid anything called essence. 
Variations 
  • Use a darker sugar – 100% soft light brown sugar – or half dark brown or muscovado and half white granulated
  • Add a tot of rum or whisky to the finished custard and blend for another minute. This might make the custard curdle once first added but it will blend out.
  • Add a teaspoon of good quality instant coffee powder for a coffee custard.
  • Add a couple of teaspoons of cocoa for a chocolate custard
  • For a super glossy rich custard sauce pulse a knob of butter through at the end of cooking.
Storage
Fridge – Transfer to a covered container, and keep in the fridge for up to three days. Gently reheat in the microwave or in a pan on the stove top. I do not recommend freezing.
