What each ingredient does
- Fresh peas
- Provide the main body of the dish, cooking to a soft, tender texture.
- Butter
- Adds fat and richness, coating the peas and giving them a smooth mouthfeel.
- Baking soda
- Helps older peas soften faster by raising the pH of the cooking water.
The step that matters
Boiling older peas. Older peas have tougher skins and starches that take longer to soften. Adding a pinch of baking soda to the water raises its alkalinity, which helps break down pectin and speeds softening, but too much can make the peas mushy or give them a soapy taste.
