Why it works: Yam and pepper work together. They rank in the top 9% of all ingredient pairs, and 111 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Wash and dry the yams.
Bake them in a 400°F (200°C) oven until soft.
Serve on a folded napkin with butter, salt, and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yams
- Form the main body of the dish; baking softens their starchy flesh until tender.
- Butter
- Adds fat and richness that melts into the hot flesh, adding moisture and flavor.
The step that matters
Bake until soft. Yams are ready only when the starch inside has fully softened. Pulling them early leaves a firm, chalky center, while the oven's dry heat also sets a skin that needs to be dried first so it can crisp rather than steam.
