Combine the kohlrabi with the onion, salt and lime juice. Allow to sit for 20 minutes, then squeeze out any excess liquid.
In a small bowl, whisk together the eggs, garlic, ginger, pepper, and ricotta.
Add the mix to the kohlrabi mixture. Combine well and sprinkle in the flour. Fold to incorporate.
Form palm size patties. In a skillet, heat up about 2 teaspoons olive oil and cook the fritters for 3-4 minutes on each side or until golden and cooked through.
For the mango lime sauce:
Place all the ingredients in a small saucepan and simmer for about 15 minutes or until soft. If you are using fresh mango, you might need to add about ¼ cup (60 ml) water. Using a stand or hand mixer, blend until smooth.
Notes
Tip: You could swap half of the kohlrabi with grated celery root. This is another flavorful fall vegetable that we tend to forget, and it really pairs beautifully with kohlrabi.
