Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fresh Tomato Napoleon
Ingredients
Directions
Prepare
Use tomatoes held at room temperature until fully ripe.
Cut a thin slice from the bottom of each tomato and discard; then cut remaining tomatoes into 4 slices each; set aside.
In a small bowl, mix oil, lemon juice, mustard, salt and sugar until well blended for dressing.
In a medium bowl, toss greens with about a tablespoon of the dressing.
Assemble and serve
On each of 4 plates, place a bottom tomato slice.
Sprinkle lightly with cheese and greens.
Repeat layering 3 more times ending with the top tomato slice.
Drizzle with remaining dressing.
Serve as an appetizer, with grilled beef or chicken, on a salad plate with cheese and fish salad, etc.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the juicy, acidic base layers that carry the dressing and cheese.
- Olive oil
- Adds fat and richness to the dressing, carrying flavor across the greens and tomato.
- Lemon juice
- Adds acidity that brightens the dressing and balances the sweetness of the tomatoes.
- Powdered mustard
- Helps emulsify the dressing so the oil and lemon juice blend smoothly.
- Cheese
- Adds salty, savory richness that contrasts with the acidic tomatoes.
- Salad greens
- Add fresh texture and bulk between the tomato layers.
The step that matters
Use fully ripe tomatoes at room temperature. Cold tomatoes have muted flavor and firmer texture, and ripe fruit at room temperature is juicier and sweeter, which makes the layers taste balanced.
Swap the lemon
How well each one fits the dish's main ingredients (tomato, olive, mustard, sugar, pepper, lettuce, feta cheese):
- Avocadofits better
- Limefits about as well
- Cherryfits about as well
