Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Mash the greens well.
Mix and heat
Add salt, pepper, butter, and cream or milk to the mashed greens.
Place the raw onion in the center of the mixture.
Heat over a clear fire until hot and dry enough to mold.
Remove the onion before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sprouts or greens
- Provide the main bulk and green flavour, and are mashed into a soft base.
- Butter
- Adds fat for richness and a smooth, savoury mouthfeel.
- Cream or milk
- Adds moisture and softness so the mashed greens blend together.
- Raw onion
- Infuses a sharp aroma into the mixture while it heats and is removed before serving.
The step that matters
Heating until dry enough to mold. The mixture must lose enough surface moisture to hold its shape, but heating too long over a fierce fire can scorch it or dry it out. Heat gently and check that it holds together when pressed.
Swap the onion
