Spanish Beans
Ingredients
Directions
Prepare the beans
Soak the beans overnight with baking soda.
Bring the beans to a boil in the same water, then rinse thoroughly.
Cook
In a pot, combine the strained tomatoes, ground mustard, brown sugar, minced onion, red sweet pepper or pimentos, salt, red pepper, and olive oil.
Add enough water to cover the beans and cook in a strausky or fireless cooker.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Italian beans
- Form the main body of the dish and absorb the tomato sauce as they cook.
- Baking soda
- Softens the bean skins during soaking so they cook more evenly.
- Strained tomatoes
- Provide the liquid base and acidity that flavour the beans.
- Brown sugar
- Adds sweetness that balances the acidity of the tomatoes.
- Olive oil
- Adds fat that carries flavour and gives the sauce a richer mouthfeel.
