Why it works: Spinach and tomato match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 1,350 recipes mention both. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
The recipe
Serves 4Ingredients
Contains: milk, wheat (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.
Heat the oven to 200°C (400°F). Brush both sides of the aubergine slices with 1 tablespoon of the olive oil.
Heat a frying pan or grill pan over medium-high heat. Cook the aubergine slices in batches for about 3 minutes per side until golden and soft. Set aside to cool slightly.
Put the spinach in a large pan with a splash of water over medium heat. Stir for 2 to 3 minutes until wilted. Drain well, squeeze out the excess liquid and chop finely.
In a bowl, mix the spinach with the ricotta, a grating of nutmeg and half of the Parmesan or vegetarian alternative.
Spread the tomato sauce over the base of a baking dish about 20 x 30 cm (8 x 12 in).
Spoon a line of the spinach mixture across the wide end of each aubergine slice and roll up tightly. Place the rolls seam-side down in the dish.
Mix the breadcrumbs, the remaining Parmesan or alternative and the remaining 1 tablespoon of olive oil. Sprinkle over the rolls and bake for 20 to 25 minutes until golden and bubbling. Rest for 5 minutes before serving.

Fit is the average pairing score against olive, spinach, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
