This slaw-style salad is based on a traditional grated carrot salad that is ubiquitous in france. It's sold at traiteurs across the country, made of grated carrots and almost always augmented with raisins. Adding grated kohlrabi to the mix gives this recipe a peppery, crisp edge. Plus, the raisins are left out to let the carrots do the heavy lifting on the sweetness front. Kohlrabi is a member of the cabbage family that has two outer layers that must be peeled. If your kohlrabi comes with leaves attached, they are edible and can be used as you would use collard greens or kale. Kohlrabi is high in vitamin c and vitamin b6, while carrots will provide vitamin a, vitamin k, and vitamin b6.
