Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Lalla Rookh Punch
Ingredients
Directions
Make the custard
Scald the milk in a double boiler until the water in the outer kettle boils.
Beat the egg yolks and sugar together until light and smooth.
Slowly stir the scalded milk into the beaten egg yolks and sugar.
Return the mixture to the double boiler and cook, stirring constantly, until it thickens enough to coat the spoon. Do not let it boil or cook too long to avoid curdling.
Remove the custard from the stove, add the cream and vanilla, and stir until partly cold.
Freeze and finish
When cold, freeze the mixture, then add the rum or maraschino wine.

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 as they cook and add richness and smooth body.
- Milk
- Forms the liquid base of the custard that thickens with the yolks.
- Cream
- Adds fat for a richer, smoother texture in the frozen mixture.
- Sugar
- Sweetens the custard and helps keep the frozen texture soft.
- Rum or maraschino wine
- Adds flavor and alcohol, which also keeps the frozen mixture from freezing solid.
The step that matters
Cooking the custard without boiling. Egg yolks thicken as they heat, but past a point they curdle and turn grainy. Cook gently, stirring constantly, and stop once the custard coats the spoon.
