Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tinned Ham or Sausage Croquettes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Pass the ham, boiled potatoes, and onions through a hash machine.
Season the mixture with pepper and mold it into cakes.
Coat and cook
Beat the butter and eggs together to form a batter.
Cover the cakes with the batter.
Place the cakes in greased pans and bake at 400°F (200°C) until brown.
Alternatively, fry until brown.
Serve
Serve with stewed tomatoes or tomato sauce.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Provides the main savoury, meaty flavour of the filling.
- Boiled potatoes
- Bind the filling and give the cakes a soft, moist body.
- Butter
- Adds richness and helps the coating brown in the oven or pan.
- Eggs
- Bind the batter so it coats the cakes and sets when cooked.
- Onions
- Add aromatic sweetness and savour to the filling.
The step that matters
Coating the cakes with batter. If the batter is too thin or the cakes are wet, the coating slides off or cooks unevenly. Egg proteins set with heat to hold the coating in place, so the cakes should be well formed and evenly covered before baking or frying.
Swap the tomato
