Why it works: Beans and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,733 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Boston Baked Beans
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
Boil the beans until almost tender, then drain.
Layer and season
In a covered baking dish, layer the beans and bacon, repeating until full.
Sprinkle with pepper and coarse sea salt.
Add the butter and dark brown sugar.
Bake
Cover well with water and bake for several hours at 350°F (175°C), replenishing water as necessary.
Remove the cover during the last hour to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the bulk of the dish and soften into a tender, starchy base as they bake.
- Breakfast bacon
- Adds fat and smoky, savoury flavour that seeps into the beans during baking.
- Dark brown sugar
- Adds sweetness and molasses flavour, and helps the surface caramelise and brown.
- Butter
- Adds richness and fat, giving the beans a smoother, rounder mouthfeel.
The step that matters
Replenishing the water during baking. Beans need enough liquid for the long bake; if the dish dries out, the beans can scorch and toughen instead of becoming creamy and tender.
Swap the beans
How well each one fits the dish's main ingredients (pepper, egg, butter, sugar):
- Almondfits better
- Walnutfits better
- Chestnutfits about as well
- Beansthe original
Fit is the average pairing score against pepper, egg, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
