Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Uma Bean Loaf
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the beans
Soak the beans overnight in cold water, then drain.
Cover the beans with boiling water.
Add the onion, carrot, and rice.
Cook until the beans are tender.
Drain the mixture, reserving the water for soup stock.
Pass the bean mixture through a meat chopper.
Mix and bake
Add the remaining ingredients and mix well.
Pack into a greased bread pan.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried lima beans
- Provide the main body and protein-rich bulk that holds the loaf together.
- Rice
- Absorbs liquid and adds starch, helping the loaf set firm when baked.
- Onion
- Adds savory depth and moisture as it softens during cooking.
- Carrot
- Adds moisture and mild sweetness, and helps bind the mixture.
The step that matters
Pass the bean mixture through a meat chopper. Mashing the cooked beans finely lets them bind with the rice and other ingredients. Coarse pieces won't hold together, so the loaf can crumble when sliced.
Swap the lima beans
How well each one fits the dish's main ingredients (onion, carrot, mustard, rice, ketchup):
- Beansfits better
- Sesamefits better
- Lentilsfits better
- Lima beansthe original
Fit is the average pairing score against onion, carrot, mustard, rice, ketchup. Candidates are from the same food group and used in at least 100 recipes.
