Ingredients
Directions
Prepare
Remove roots from the spinach and wash it thoroughly in several waters to remove sand.
Cook
In a stew pan, bring 2 quarts of water to a boil and add salt, sugar, and baking soda.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the bulk of the dish and wilts to a soft, tender texture when boiled.
- Butter
- Adds richness and a smooth, silky mouthfeel to the chopped greens.
- Baking soda
- Raises the water's alkalinity, helping the spinach keep a bright green color while cooking.
The step that matters
Drain the spinach well. Spinach holds a lot of water after boiling. Excess moisture dilutes the butter and makes the dish watery, so it should be squeezed or pressed dry before chopping and seasoning.
Swap the spinach
How well each one fits the dish's main ingredients (sugar, butter, bread):
- Leekfits better
- Sweet potatofits better
- Capsicumfits better
- Spinachthe original
Fit is the average pairing score against sugar, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
