Ingredients
Directions
Make the custard
Beat the eggs well and stir in the flour.
Strain the egg mixture through a sieve into the milk.
In a skillet, heat the brown sugar until it boils.
Add the egg and milk mixture to the boiling sugar and cook for 2-3 minutes.
Season with cinnamon in a muslin bag and boil in the custard.
Chill and freeze
Once the custard is cold, freeze it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving it body and a thick, creamy texture.
- Flour
- Thickens the egg mixture and helps keep the custard smooth rather than grainy.
- New milk
- Forms the liquid base of the custard and adds richness and creaminess.
- Light brown sugar
- Melts and caramelises in the skillet, giving the custard its burnt sugar flavour.
The step that matters
Cooking the custard over the boiling sugar. Egg proteins set with heat, so the mixture must be cooked gently and stirred to avoid curdling or scrambling. Cooking it for just the stated 2-3 minutes helps keep it smooth.
