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

What each ingredient does

Calf's foot isinglass
Sets the liquid into a firm, wobbly gel as it cools.
Milk
Forms the liquid base and gives the dessert its creamy body.
Crushed sugar
Adds sweetness to balance the milk and flavoring.

The step that matters

Boil slowly. Isinglass must dissolve completely in the hot milk to set properly. Gentle heat helps prevent the milk from scorching on the bottom of the pan or boiling over.

Swap the lemon

How well each one fits the dish's main ingredients (milk, sugar):

  1. Vanillafits better
  2. Figfits better
  3. Peachfits better
  4. Lemonthe original

Fit is the average pairing score against milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
