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

What each ingredient does

Buttermilk
Provides the tangy liquid base that the drink is built on.
Sugar
Sweetens the base and lowers its freezing point, keeping the drink softer when frozen.
Eggs
Add richness and body, with separately beaten whites giving a lighter texture.
Orange juice
Adds fruity sweetness and aroma to the drink.
Lemon juice
Adds acidity that brightens the flavour and balances the sugar.

The step that matters

Freeze in the usual way, packing in ice and salt for an hour before serving. Salt lowers the temperature of the ice bath, so the mixture freezes evenly. Sugar also lowers the freezing point, so the drink stays soft enough to scoop and serve.

Swap the orange

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

  1. Vanillafits about as well
  2. Orangethe original
  3. Raisinfits about as well
  4. Blueberryfits less well

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