Florentine Ice Cream

Ingredients

Directions

Make the custard

  1. Make a custard by combining the egg yolks, orange rind, and boiling syrup in a bowl.

  2. Beat the mixture with an egg beater, ensuring it does not boil.

  3. Add the cream and mix well, then strain the mixture.

Freeze and serve

  1. Freeze the mixture for 2 hours.

  2. Turn out the ice cream from the mold onto a dish.

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

What each ingredient does

Egg yolks
Thicken the custard and add richness and structure as they set gently with heat.
Boiling syrup
Sweetens the base and helps keep the custard smooth and dissolved.
Cream
Adds fat and richness, giving the frozen ice cream a smooth, creamy texture.
Orange rind
Adds aromatic citrus flavour from the oils in the peel.

The step that matters

Beat the custard without letting it boil. Egg yolks scramble and curdle when overheated, which makes the custard grainy. Keeping it below boiling lets it thicken smoothly.

Swap the orange

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

  1. Vanillafits better
  2. Raisinfits better
  3. Strawberryfits better
  4. Orangethe original

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