Koufeto is a traditional sweet preserve or spoon sweet (glyko tou koutaliou) from the island of Milos. It is made by simmering pieces of local sweet white pumpkin in a mixture of water, sugar, and local honey, which is then combined with blanched almonds and lemon juice.

The preserve is typically kept in glass jars, and it is sometimes flavored with cinnamon sticks. On Milos, this sweet specialty is usually associated with weddings and engagements, which is how the preserve earned its name the marriage sweet.

Koufeto is usually enjoyed on its own, accompanied by a glass of cold water on the side to balance the sweetness. It is also often served with ice cream or yogurt.
