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

What each ingredient does

Isinglass
Gelatin-like protein that sets the milk mixture into a firm, sliceable jelly as it cools.
Milk
Provides the creamy body and base of the dessert.
Sugar
Adds sweetness to the milk base.
Lemon
Its juice adds a bright acidity that balances the sweet, rich milk.

The step that matters

Dissolving the isinglass in the boiling mixture. Isinglass must be fully dissolved into the hot milk so it sets evenly. Undissolved specks will leave weak spots and an uneven texture once the mold chills.

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.
