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 ↓
Beans, Butter
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, or boil them in cold water for a few hours if they are newly picked.
Drain the beans and place them in a pie dish.
Season and bake
Sprinkle with pepper, coarse sea salt, and tomato sauce.
Add a lump of butter and some bacon rinds.
Bake in a 350°F (175°C) oven for about 30 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Sauce and butter barely smell alike, yet cooks put them together in 15,338 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
- Beans
- Form the main body of the dish, becoming soft and tender as they cook.
- Tomato sauce
- Adds moisture and acidity, flavouring the beans as they bake.
- Butter
- Adds richness and fat, helping the beans taste rounder and browning the surface.
- Bacon rinds
- Release fat and savoury flavour into the beans during baking.
The step that matters
Soaking or boiling the beans. Dried beans must be fully softened before or during baking. Beans that are not soaked or cooked long enough stay firm and can taste starchy, so the soaking step matters most.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
