Steamed Custard

Ingredients

Directions

Mix the custard

  1. Beat the egg lightly in a bowl.

  2. Mix in the milk.

  3. If desired, add sugar for sweetness or a pinch of salt for flavor.

Steam and set

  1. Butter a cup and pour in the mixture.

  2. Steam in boiling water until set, being careful not to overcook to avoid curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg
Its proteins set when heated, giving the custard its firm, sliceable structure.
Milk
Adds liquid and dilutes the egg, keeping the set custard soft and tender rather than rubbery.

The step that matters

Steam until just set. Egg proteins coagulate as they heat, forming the custard. If heated too long or too hot, they tighten too much, squeezing out water and causing curdling, a grainy texture and weeping.
