Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Cucumbers, Boiled

Ingredients

Directions

Slice the cucumbers, leaving the stalk end intact to preserve flavor.
Sprinkle with coarse sea salt and let sit to draw out moisture.
Drain the moisture and season with black pepper, vinegar, and olive oil.
For a refreshing variation, mix sliced cucumbers with sugar and lemon juice.
Serve immediately or let sit for a few hours to enhance flavors.
