Why it works: Vanilla and milk 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 ↓
Butterscotch Apples
Ingredients
Directions
Prepare the apples
Wash the apples, cut them into quarters, and remove the skin and core.
Cook the apples in syrup
In a saucepan, combine the brown sugar and water, and heat until boiling.
Add the apples to the boiling syrup, cover, and simmer until tender.
Remove the apples with a skimmer and place them in serving dishes.
Make and finish the sauce
In another pan, mix the milk and corn starch until smooth.
Stir and cook the mixture until it reaches a boil, then add it to the syrup with the apples.
Boil for a few minutes, then stir in the salt, butter, and vanilla.
Pour the sauce over the apples and serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main body and texture once cooked until tender in the syrup.
- Brown sugar
- Forms the sweet, caramel-flavoured syrup that the apples cook in.
- Milk
- Forms the creamy base of the butterscotch sauce.
- Corn starch
- Thickens the milk mixture so it becomes a smooth, pourable sauce.
- Butter
- Adds richness and fat for a silkier, more rounded sauce flavour.
The step that matters
Mixing and cooking the cornstarch mixture. Cornstarch must be fully smoothed into the cold milk before heating, then brought to a boil, or it will form lumps instead of a smooth thickened sauce. Starch thickens only once heated enough to swell its granules.
Swap the apple
How well each one fits the dish's main ingredients (sugar, vanilla, milk, corn, butter):
- Coconutfits better
- Figfits better
- Peachfits better
- Applethe original
Fit is the average pairing score against sugar, vanilla, milk, corn, butter. Candidates are from the same food group and used in at least 100 recipes.
