Why it works: Potato and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 8,303 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that becomes smooth and fluffy when mashed.
- Cream
- Adds moisture and richness, making the mash softer and smoother.
- Butter
- Adds fat for richer flavour and a silkier texture.
The step that matters
Mash the potatoes until smooth. Overworking cooked potatoes releases excess starch, which can turn them gluey. Mash gently and stop once smooth, then fold in the cream and butter.
