Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Portuguese Baked Beans
Ingredients
Directions
Prepare
Soak the beans overnight.
Cut the chouriço into small chunks and marinate in red wine vinegar overnight.
In the morning, rinse the beans and place them in a pan large enough to cover them; add the chopped onion and the marinated chouriço, then cover with water.
Bake and finish
Bake at 350°F for 3–4 hours or until the beans are cooked.
Remove the beans and stir in tomato sauce (or ketchup to taste); return to the oven until all liquid is absorbed, about 45 minutes.
Check on them; you can also cook them in a crock pot, then finish in the oven to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Form the body of the dish, becoming soft and creamy as they cook slowly.
- Chouriço
- Adds smoky, savory fat and flavor that seasons the beans as they bake.
- Tomato sauce
- Adds moisture and acidity that thicken into a rich, saucy coating as liquid reduces.
- Onion
- Contributes sweetness and aromatic depth as it softens during the long cook.
The step that matters
Stir in tomato sauce and bake until the liquid is absorbed. Adding tomato sauce late, after the beans are cooked, keeps the acidity from slowing their softening. Baking until the liquid is absorbed concentrates the flavor and gives a thick, glossy sauce rather than a soupy result.
Swap the onion
How well each one fits the dish's main ingredients (beans, red wine, vinegar, tomato, sauce):
- Capsicumfits better
- Cucumberfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against beans, red wine, vinegar, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
