Kale can sometimes taste bitter, especially if it’s not massaged properly. In addition to massaging the leaves, you can balance the bitterness with sweet or tangy ingredients. In this recipe, cranberries add a nice sweetness, and the avocado helps create a creamy texture that cuts through the bitterness. You can also use a bit more lemon juice in the dressing or add a drizzle of honey or maple syrup to sweeten the salad.
