Why it works: Spinach and nutmeg match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 603 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Potatoes and Spinach
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 filling
Boil the potatoes until tender, then mash them.
Boil the spinach, chop it finely, and mix it with the mashed potatoes.
Add salt, pepper, nutmeg, and sweet butter to the mixture.
Combine everything thoroughly and transfer to a pie dish.
Bake
Bake in a 350°F (175°C) oven until the top is golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the casserole, giving a soft, starchy body once mashed.
- Spinach
- Adds moisture and a green, earthy flavor to the mashed base.
- Sweet butter
- Adds richness and fat, giving the mash a smoother texture and flavor.
The step that matters
Bake until the top is golden brown. Browning on the surface comes from the Maillard reaction, which needs dry heat. Watching the color rather than only the clock helps the top brown without drying the interior.
