Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Cider Soup
Ingredients
Directions
Make the soup base
Boil the cider in a pot and skim off any foam.
Stir in ½ cup of sugar.
Prepare the bread and custard
In a skillet, brown the diced bread in butter.
In a bowl, beat the eggs and mix in 2 tablespoons of sugar, 2 tablespoons of flour, and 1½ cups of milk.
Finish the soup
Add the egg mixture and whole allspice to the boiling cider.
Finally, stir in the browned bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider
- Forms the liquid base and provides the main apple flavour of the soup.
- Eggs
- Thicken the soup as they set with heat, giving it body.
- Flour
- Helps thicken the egg and milk mixture so it blends smoothly into the hot cider.
- Milk
- Adds richness and softness, mellowing the cider's sharpness.
- Bread
- Browned in butter, it adds texture and toasted flavour that holds up in the soup.
The step that matters
Adding the egg mixture to the boiling cider. Eggs can curdle or scramble if they meet very hot liquid directly. Whisking a little hot cider into the egg mixture first gently raises its temperature, helping it blend smoothly and thicken evenly.
Swap the allspice
How well each one fits the dish's main ingredients (cider, sugar, bread, butter, egg, flour, milk):
- Cinnamonfits better
- Nutmegfits better
- Capersfits about as well
- Allspicethe original
Fit is the average pairing score against cider, sugar, bread, butter, egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
