Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Preserved Meat
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the meat and onions into pieces.
Cook the onions until tender.
Make the batter
Prepare a batter with the eggs and milk, seasoning with half the salt and pepper.
Grease a baking dish and pour in half the batter.
Place the dish in the oven until the batter sets.
Assemble and bake
Add the meat and cooked onions on top of the batter.
Cover with the remaining batter and seasoning.
Bake for 15 to 20 minutes at 400°F (200°C).

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and help it set firm in the oven.
- Flour
- Forms the batter's structure as it cooks and sets.
- Milk
- Hydrates the flour and keeps the batter moist and pourable.
- Suet
- Adds fat that enriches flavor and keeps the dish moist.
- Meat
- Forms the main filling and contributes savory flavor and richness.
The step that matters
Placing the dish in the oven until the batter sets. If the base batter is not set before the meat goes on, the filling can sink into it and the layers will blend unevenly. Setting the first layer gives the casserole a firm base.
Swap the onion
How well each one fits the dish's main ingredients (meat, flour, pepper, egg, milk):
- Capsicumfits better
- Asparagusfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against meat, flour, pepper, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
