Why it works: Walnut and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 491 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Waldorf Salad
Ingredients
Directions
Make the salad
In a bowl, mix equal quantities of diced apple and diced celery.
Add the walnut meats and moisten with mayonnaise dressing.
Assemble and serve
Remove the tops from red or green apples and scoop out the inside pulp, leaving enough to keep the apples in shape.
Refill the apple shells with the salad and serve on lettuce leaves.
