Which type of nuts?You can use a variety of nuts to make the nut burgers. We often use a mix walnuts, cashews and peanuts, but other kinds would work just as well.Can I cook these in the oven?We haven't had the best results trying to cook the burgers in the oven. Cooking the burgers in a frying pan works best, and is also easy and quicker.If you want to try cook these in the oven, place them on greaseproof paper, brush them with some oil. Grill them until brown on the top and carefully turn over, and continue to grill the other side.
