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

What each ingredient does

Mung beans
Cooked and blended, they give the custard its body and creamy, thick texture.
Eggs
Set during baking to give the custard structure and a firm, sliceable texture.
Coconut cream
Adds fat and richness, making the custard smooth and creamy.
Coconut or palm sugar
Adds sweetness and a caramel-like depth of flavour, and helps browning on top.
Granulated sugar
Adds sweetness and helps the custard brown at the surface.

The step that matters

Bake until the center is just firm. Eggs set as they heat, so pulling the custard too early leaves it runny, while overbaking makes it dense, rubbery and prone to cracking.

Fit is the average pairing score against coconut, mung bean, chicken, sugar, cream. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
