Why it works: Spinach and pepper are a kitchen classic. They rank in the top 4% of all ingredient pairs, and 3,400 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓
The recipe
10 servingsIngredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Place the baby spinach in a large pot with only the water clinging to the leaves after washing. Cook over medium-high heat, stirring, until wilted, about 4 minutes.
Tip the wilted spinach into a colander and press out as much liquid as you can with a spoon or your hands. Chop it roughly.
Return the pot to medium heat. Add the chopped onion and cook, stirring, until softened, about 4 minutes.
Pour in the heavy cream and bring to a gentle simmer. Cook for about 5 minutes until slightly thickened.
Stir in the spinach and simmer for 3 minutes so it absorbs the cream.
Season with kosher salt and a pinch of cayenne pepper to taste. Serve hot.
