Are you talking about the jicama fries or the cottage cheese chip? For the jicama fries you first have to boil them until they are soft... then dry them on a paper towel. I used my air fryer, but you can use an oven. I cooked them at 400 degrees in my air fryer for like 15 minutes with avocado oil, salt, and dill weed, turn them around halfway through so both sides cook. For the cottage cheese chips it's a silicone dish, I bought at Walmart. Mine looked like this Silicone Dish obviously mine didn't cost $28... that's just an example.
