Why it works: Lentils and flour match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 255 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Lentil Stew
Ingredients
Directions
The book says “a warm oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash and pick the lentils clean.
Place lentils in a deep pie dish with 1 quart of water.
Cook the lentils
Put in a warm oven and gradually increase the heat to 400°F (200°C) for about 2 hours.
Add more boiling water as needed to prevent drying out.
Once soft and pulped, stir in olive oil, salt, and pepper.
Finish the stew
Add cold boiled rice, chopped potatoes, and sift in wholemeal flour.
Incorporate crusts of stale bread dipped in milk or water.
Stir everything together and boil for about 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egyptian lentils
- Form the main body of the stew and break down into a thick pulp as they cook.
- Cold boiled rice
- Adds body and thickens the stew as its starch absorbs liquid.
- Cold potatoes
- Add starch that helps thicken the stew and gives it a softer, heartier texture.
- Wholemeal flour
- Thickens the stew by absorbing liquid and binding the ingredients together.
- Stale bread crusts
- Soak up liquid and add body, helping the stew thicken further.
- Olive oil
- Adds richness and fat, carrying flavour and smoothing the texture.
The step that matters
Adding more boiling water during the long cook. Lentils absorb water as they simmer and can scorch or dry out in a hot oven. Adding boiling water keeps the mixture moist so the lentils soften evenly instead of sticking and burning.
