Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and 8,305 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Eggs with Vegetables
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the base
Prepare mashed potatoes or finely chopped cooked spinach, seasoned with butter, pepper, and coarse sea salt.
Place the mixture in a buttered casserole and smooth the top, making a depression for each egg.
Bake and serve
Break each egg into a saucer and carefully slip it into the hollow formed; season lightly.
Bake in a moderate oven at 350°F (175°C) until the whites are set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when baked, forming the tender, cooked centre of the dish.
- Mashed potatoes or cooked spinach
- Forms the soft base that holds the eggs and adds moisture.
- Butter
- Adds richness and fat, and keeps the base from sticking to the casserole.
The step that matters
Slipping the eggs into the hollows. Eggs slid in carefully stay whole and sit neatly in their wells. Breaking them directly into the dish can spread the whites and break the yolks. Egg whites set as proteins coagulate with heat, so the whites firm while the yolks stay soft.
Flavor stand-ins for the potato
How well each one fits the dish's main ingredients (butter, pepper, egg):

- Chiveabout as good a flavor fit
- Potatothe original
Fit is the average pairing score against butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
