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

What each ingredient does

Eggs
Set the curd and give it a rich, custardy structure as they cook.
New milk
Forms the body of the curd and carries the flavour of the cinnamon.
Butter
Adds fat for a smoother, richer texture.
Pounded sugar
Adds sweetness and balances the tartness of the wine.

The step that matters

Strain after the mixture boils again. Egg proteins can scramble if the mixture overheats, leaving lumps. Straining through a sieve removes any set bits so the curd stays smooth.

Swap the orange

How well each one fits the dish's main ingredients (milk, cinnamon, egg, white wine, butter, sugar):

  1. Vanillafits better
  2. Applefits better
  3. Figfits better
  4. Orangethe original

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