Why it works: Peas and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 4,887 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

What each ingredient does
- Split peas
- Their starch thickens as they cook, giving the stew its body and mushy texture.
- Nut butter
- Adds fat and richness, rounding out the flavor of the peas.
The step that matters
Add hot water as needed to prevent burning. Split peas are starchy and thicken as they swell, so the bottom of the pot can scorch. Adding hot water keeps the liquid level up and reduces sticking, while hot water keeps the simmer going without stalling the cooking.
