Why it works: Horseradish and lettuce share more aroma than cooks usually use. They rank in the top 2% of all ingredient pairs, and cooks put them together in 79 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Grilled Tofu Sandwiches
Ingredients
Directions
Prepare the tofu
Use firm, Chinese-style tofu and marinate it for several days.
Prepare the grill and grill the tofu on both sides about 6 inches above the coals until well-browned and slightly crispy; if not grilling, broil the tofu on both sides.
Slice the tofu in half crosswise to make 1/2-inch thick pieces and cut them to fit the bread.
Assemble the sandwich
Spread mayonnaise and horseradish on the bread slices.
Arrange tomato slices on the tofu, season with salt and pepper, and add red onions if desired.
Top with lettuce and the second slice of bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm tofu
- Provides the main protein and chewy body, and browns and crisps on the grill or under the broiler.
- Tomato
- Adds juicy moisture and a fresh acidic brightness that balances the rich tofu and mayonnaise.
- Mayonnaise
- Adds fat and creaminess, moistening the bread and carrying the horseradish flavor.
- Bread
- Provides the structure that holds the filling together and soaks up some moisture from the toppings.
The step that matters
Grilling or broiling the tofu until well-browned. Tofu is mostly water and bland until its surface dries and browns. Browning through the Maillard reaction develops savory flavor and a slightly crisp texture that contrasts with the soft bread and toppings.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (tofu, wheat, horseradish, tomato, pepper, lettuce):
- Spinachfits better
- Mustardfits better
- Broccolifits better
- Onionthe original
Fit is the average pairing score against tofu, wheat, horseradish, tomato, pepper, lettuce. Candidates are from the same food group and used in at least 100 recipes.
