Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
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.
Prepare
Boil and mash the potatoes.
Season with salt and pepper.
Form the mixture into balls.
Brush and bake
Brush the balls with the beaten egg yolk while hot.
Grease a baking pan with butter.
Bake in a 400°F (200°C) oven for 5 to 10 minutes until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Starch gives the puffs their body and a soft, tender interior.
- Egg
- Beaten egg brushed on the surface promotes browning and a glossy finish.
The step that matters
Bake until browned. Browning happens quickly at this oven temperature, so the puffs can scorch on the outside before the centre is heated through. Check them near the start of the 5 to 10 minute window.
Swap the potato
