What foods are flammable?

Question

My son is doing a science fair expirement for school and it is 80% of his monthly grade. He wants to do a calometer (caloriemeter) to test the amount of calories in different foods. He and I cannot brainstorm a whole lot of flammable foods. I thought testing different kinds of nuts (pecans,walnuts,peanuts) or testing the different french fry brands might be good. Do those work? Does anybody have an idea of a series of related foods that he could use in his projuect. THANKS!
