Ingredients

Directions

Make the syrup

  1. Boil 8 pounds of sugar in 1 pint of water until it forms a good syrup.

  2. Add enough yellow food coloring to achieve a yellow color.

  3. Let the syrup cool, then mix in the yolks of 6 eggs.

Freeze and serve

  1. Freeze the mixture until solid.

  2. Serve with yellow flowers like jonquils, butter cups, roses, pansies, or nasturtiums.

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

What each ingredient does

Sugar
Dissolved in water to make the syrup, providing sweetness and body to the frozen mixture.
Yolks of eggs
Add richness and emulsifying power, giving the frozen dessert a smoother, creamier texture.
Orange juice
Provides the main flavor and acidity of the frappe.

The step that matters

Freezing until solid. Sugar syrup and egg yolks freeze slowly and form ice crystals, so the texture depends on how the mixture is cooled and frozen. Cooling the syrup fully before adding the yolks keeps the eggs from cooking.

Swap the pineapple

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

  1. Vanillafits better
  2. Limefits better
  3. Blueberryfits about as well
  4. Pineapplethe original

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