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 Gravy with Rice
Ingredients
Directions
Prepare the lentils
Rub the cooked lentils through a colander to remove the skins.
Make the gravy
In a saucepan, combine the lentils with the rich milk and cream if using.
Add salt to taste and heat the mixture to boiling.
In a small bowl, mix the flour with a little cold milk until smooth.
Add the mixture to the boiling lentil mixture to thicken.
Serve
Serve hot over nicely steamed or boiled rice, or with well cooked macaroni.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked lentils
- Form the body of the gravy and give it its earthy, thick texture once pureed.
- Rich milk
- Adds moisture and richness, creating a smooth, creamy base for the gravy.
- Flour
- Thickens the liquid as it heats, giving the gravy body and a smooth consistency.
The step that matters
Adding the flour mixture to the boiling lentils. Flour must be fully blended in cold milk first, then added to boiling liquid while stirring. This lets starch granules swell evenly and thicken without forming lumps.
Swap the lentils
How well each one fits the dish's main ingredients (milk, cream, flour, rice):
- Almondfits better
- Pistachiofits better
- Cashew nutfits better
- Lentilsthe original
Fit is the average pairing score against milk, cream, flour, rice. Candidates are from the same food group and used in at least 100 recipes.
