Cooking without an oven and freezer? Is that possible to have them in a forest?

Yes, with the help of Straight Arrow, you can get an oven and freezer near your camp fire. For making a freezer, dig a hole in earth, cover the place with stones and put your food or pots inside these stones, and then cover it with latch sticks, and grass or straws on the top of it. For more safety, make a fence around it. And your freezer is ready which will keep your food safe and cold.
