Why it works: Beans and lentils match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 135 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Lentil Loaf
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Run the beans, lentils, and peas through a colander.
Add the melted butter, fried onions, and beaten eggs.
Rub the peanut butter to a cream in a little hot water and add it to the mixture.
Finally, add the summer savory and bread crumbs, and mix well.
Oil a loaf pan and pour the mixture into it.
Bake
Bake in a hot oven at 400°F (200°C) for 45 minutes to 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and help it set firm when baked.
- Lentils
- Provide the bulk and protein-rich body of the loaf.
- Bread crumbs
- Absorb moisture and help the loaf hold its shape.
- Butter
- Adds fat for richness and a softer, moister texture.
- Fried onions
- Add savory flavour and moisture to the mixture.
The step that matters
Mixing in the peanut butter. Creaming peanut butter with hot water thins it so it blends evenly; lumps left unblended can create dense pockets in the loaf.
Swap the onion
How well each one fits the dish's main ingredients (beans, lentils, peas, butter, bread, egg, peanut):
- Asparagusfits better
- Spinachfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against beans, lentils, peas, butter, bread, egg, peanut. Candidates are from the same food group and used in at least 100 recipes.
