Why it works: Leek and onion match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,326 recipes. Both carry ethyl butyrate, which smells apple, fruity. The science ↓
Meat Hash, Prom the Fan or in Balls
Ingredients
Directions
Prepare the hash
Chop the leftover meat very fine.
Season with parsley, leeks, onions, bread crumbs, and beaten eggs.
In a stewpan, melt butter or lard and add a pinch of flour.
Add the meat mixture and moisten with broth.
Let it stew over gentle heat for 30 minutes.
Crust and serve
Spread the hash on a plate and place it on the stove until slightly crusted.
For balls, mix in sausage meat and additional egg yolks.
Form balls, dip in egg whites, coat with flour, and fry until golden.
Serve hot, garnished with parsley or sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover meat
- Forms the bulk of the hash and provides its savory, meaty flavor.
- Bread crumbs
- Absorb moisture and help bind the hash into a cohesive mass.
- Eggs
- Bind the mixture together and help it set as it cooks.
- Butter or lard
- Adds fat for richness and helps the hash brown on the surface.
- Leeks and onions
- Add aromatic sweetness and savory depth as they soften.
The step that matters
Stewing over gentle heat. Gentle heat lets the broth and bread crumbs soak into the finely chopped meat and the eggs set evenly. High heat can toughen the eggs and scorch the fat before the hash is moist and cohesive.
