Why it works: Lettuce and mustard 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 ↓
Potato Salad
Ingredients
Directions
Mix coarse sea salt thoroughly with minced warm potatoes before adding dressing.
Wash the lettuce under cold running water and let it dry.
Chill all salad ingredients thoroughly.
Stir mayonnaise with an egg beater for quick mixing.
For smooth dressing, blend flour and sugar dry, then add boiling water and stir.
If dressing curdles, add cold water and stir quickly.
Heat vinegar before adding to dressing to prevent curdling.
Mix mustard with milk instead of water to prevent drying out.
To dispense olive oil, make a slit in the cork and prop the bottle at an angle.
