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.
