Why it works: Lentils and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,221 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Baked Lentils
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the lentils
Pick over and wash the lentils.
Soak them in water overnight.
Drain the lentils.
Place them in a stew pan with 2 quarts of cold water.
Heat slowly.
When the water boils, remove the lentils with a skimmer.
Bake
Place the lentils in a deep earthen dish with the pork and onion in the center.
Mix the salt and pepper with 1 quart of boiling water.
Add the mixture to the lentils.
Cook slowly in a moderate oven at 350°F (175°C) for 4 to 5 hours, adding a little water from time to time.
Adjust salt if the pork is not very salty.

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 dish, becoming tender and creamy as they simmer and bake.
- Salt pork
- Adds fat and savory flavor that seeps into the lentils during slow baking.
- Onion
- Adds aromatic sweetness and depth as it cooks slowly with the lentils.
The step that matters
Cook slowly and add water from time to time. Lentils can dry out or scorch during the long, slow bake. Adding water as needed keeps them moist and lets them soften evenly without breaking down into a dry, uneven texture.
Swap the lentils
How well each one fits the dish's main ingredients (pepper, pork, onion):
- Sesamefits better
- Black-eyed peafits better
- Beansfits better
- Lentilsthe original
Fit is the average pairing score against pepper, pork, onion. Candidates are from the same food group and used in at least 100 recipes.
