Why it works: Cucumber and parsley match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,564 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Boiled Cucumbers
Ingredients
Directions
Select good-sized cucumbers and peel them.
Cut the cucumbers in half and scoop out the seeds.
Cut each half crosswise into two pieces.
Boil the cucumber pieces in salted water until tender, about 30 minutes.
Drain the cucumbers and place them in a hot serving dish.
Pour white sauce over the cucumbers, seasoned with grated onion and chopped parsley.
