Why it works: Peas and mint are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Peas Dried
Ingredients
Directions
Prepare the peas
Soak the peas overnight in water with a lump of baking soda.
The next day, rinse the peas well.
Cook
Place the peas in a large piece of muslin and boil in water.
If the peas are not very soft, add a little more baking soda.
Season and serve
Once cooked, transfer the peas to a vegetable dish.
Add salt, pepper, butter, and fresh mint.
Cover and keep warm in hot water on the stove until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Form the main body of the dish, becoming tender and soft after soaking and boiling.
- Baking soda
- Raises the water's alkalinity, which helps the peas soften more fully during soaking and cooking.
- Butter
- Adds fat and richness, giving the cooked peas a smooth, mellow mouthfeel.
The step that matters
Adding more baking soda when peas are not soft. Baking soda raises alkalinity, which helps break down pea skins and cell walls. Adding too much, however, can make peas mushy and give them a soapy taste, so add only a little at a time.
Swap the mint
How well each one fits the dish's main ingredients (peas, pepper, butter):
- Parsleyfits better
- Tarragonfits about as well
- Thymefits about as well
- Mintthe original
Fit is the average pairing score against peas, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
