Why it works: Beetroot and watercress match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 143 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Potato Salad
Ingredients
Directions
Cut any leftover new potatoes into thin slices.
Place the potatoes on a dish with finely shredded salad leaves.
Toss with pepper, coarse sea salt, oil, and vinegar.
Sprinkle with finely minced parsley and shallot.
Garnish with beetroot, hard-boiled eggs cut into rings, watercress, small radishes, cucumber, or nasturtium leaves and flowers.
If using only potatoes, mix half an hour before serving; if adding salad leaves, mix just before serving.
