The leek is much more than an accompanying vegetable. It's an ancestral food that has conquered kitchens in various corners of the world thanks to its unique flavor and nutritional properties.

What is a leek and which food group does it belong to?

The leek is a vegetable from the lily family (Allium) characterized by its long, cylindrical stem, formed by white leaves and a more fibrous green part. Its flavor, milder and sweeter than onion, makes it ideal for preparations that require a delicate touch without being too strong.

Leek cultivation requires certain conditions to reach its maximum potential:

• Sizes and development factors: Leeks can reach considerable sizes, measuring up to 80 centimeters and weighing more than one kilogram under optimal conditions. The world record for the largest leek was grown in the United Kingdom, reaching a weight of 9.75 kg.
