Is there anything else I need to know about Leek?
While all parts of the leek are edible, it’s the tender white section that is preferred for cooking. 'Blanching' - is the process of denying the lower part of the stems of sunlight as they grow, this helps to increase the white section and sweeten the flavour. This is achieved by planting seedlings deeply and covering the lower stems with newspaper or a milk carton for around 2- 3 weeks before harvesting.
