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 the beans

  1. Soak the white and brown beans in cold water with a pinch of baking soda.

  2. Boil the beans until tender.

Bake and serve

  1. Add the tomatoes, bacon, onion, and water if needed.

  2. Season with pepper, coarse sea salt, and sugar to taste.

  3. Place in a 350°F (175°C) oven and bake for two hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White beans
Provide the main body and starchy texture of the finished dish.
Brown beans
Add body and a fuller, earthier flavour alongside the white beans.
Baking soda
Raises the soaking water's pH, helping the beans soften more evenly.
Tomatoes
Add acidity and moisture that give the sauce its tangy flavour.
Bacon
Adds fat and smoky, savoury flavour to the beans.
Onion
Adds sweetness and aromatic depth as it cooks down.

The step that matters

Boil the beans until tender before baking. Dry beans must be fully softened before the long, low bake; they will not become tender in the oven if they are undercooked, and acidic tomatoes added too early can slow softening, so the beans should be cooked through first.

Swap the onion

How well each one fits the dish's main ingredients (beans, tomato, pepper, sugar):

  1. Capsicumfits better
  2. Sweet potatofits better

  4. Onionthe original

Fit is the average pairing score against beans, tomato, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
