Why it works: Cucumber and sugar are a kitchen classic. They rank in the top 26% of all ingredient pairs, and cooks put them together in 3,112 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Preserved Cucumbers
Ingredients
Directions
Split the cucumbers and remove the seeds.
Soak the cucumbers in saltwater for three days.
Place them in cold water with a small amount of alum and boil until tender.
Drain the cucumbers and let them sit in a thin syrup for two days.
Reheat the syrup and pour it over the cucumbers, repeating this twice more.
Boil clarified sugar until it forms small sparks when blown through.
Add the cucumbers to the sugar and simmer for five minutes.
Let the mixture sit overnight, then boil again before storing.
