Why it works: Buttermilk and sugar match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 2,973 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Buttermilk Ice Cream
Ingredients
Directions
Mix and fill
In a large bowl, stir together the buttermilk, lemon juice, grated pineapple, and sugar until well combined.
Pour the mixture into a freezer can, leaving about 2 inches of space at the top.
Add sweet cream to fill the can to the 2-inch mark.
Freeze
Freeze the mixture and pack it as needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Adds tangy, slightly sour flavour that balances the sweetness.
- Lemon juice
- Adds acidity and brightness that lifts the flavour.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the texture softer.
- Grated pineapple
- Adds fruity flavour and moisture.
- Sweet cream
- Adds fat and richness for a smooth, creamy texture.
The step that matters
Leave the 2-inch space at the top. Ice cream expands as it freezes. Filling the can to the brim can push mixture out or make it hard to seal, so the headspace gives room for that expansion.
Swap the pineapple
How well each one fits the dish's main ingredients (buttermilk, lemon, sugar, cream):
- Vanillafits better
- Orangefits better
- Raspberryfits better
- Pineapplethe original
Fit is the average pairing score against buttermilk, lemon, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
