Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Lentil Turnovers
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
Pick and wash the lentils.
Cook the lentils in just enough water to absorb.
Peel and wash the mushrooms.
Chop the mushrooms and onion finely.
Fry the mushrooms and onion in butter.
Add the fried mushrooms and onion to the cooking lentils, along with lemon juice, pepper, and salt.
Wait until the lentils are soft.
Let the mixture cool.
Make and bake the turnovers
Make a dough with the flour, butter, and a little water.
Roll the dough out thin.
Cut the dough into 4-inch squares.
Place some lentil mixture on each square.
Moisten the edges.
Fold over.
Press to seal.
Bake the turnovers in a floured tin at 400°F (200°C) for 15 minutes.
Serve
Serve the turnovers with brown sauce, vegetables, and potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Form the bulk of the filling, becoming soft and absorbing liquid as they cook.
- Mushrooms
- Add moisture and savory, earthy flavor to the filling.
- Onion
- Adds aromatic sweetness and savory depth when fried with the mushrooms.
- Butter
- Enriches the dough with fat, giving it tenderness and a richer flavor.
- Fine wheat flour
- Provides the structure of the dough that encloses the filling.
The step that matters
Let the mixture cool before filling the dough. Hot filling softens the dough, making it tear and seep when folded and sealed. Cooling lets the lentils firm slightly and keeps the edges sealable.
Swap the onion
