Vanilla and sugar barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Carrageen moss
Its gel-forming compounds thicken the milk as it cooks, so the mixture sets into a jelly.
Milk
Forms the body of the jelly and gives it a creamy, soft texture as it sets.
Sugar
Adds sweetness to balance the mild, slightly salty milk base.

The step that matters

Cook until the milk sets. Carrageen needs to be heated long enough to release its gelling compounds into the milk. Undercooking leaves the jelly loose, while the gentle heat of a double saucepan helps prevent scorching and curdling of the milk.
