In deep snow you may have to make a platform for your fire. If you do not use a platform, the snow under and around the fire will melt and your fire will lower itself into the snow. Eventually the fire will melt enough snow to put it out. If the snow is not too deep, you may be able to dig out enough snow to build a fire, but avoid overheating as you dig the snow. You man have to remove your coat to avoid sweating, which can freeze in cold weather.
There are many different kinds of fire to cook with, but your biggest problem may be finding a container. I carry heavy-duty aluminum foil which can be used to boil with or you may be able to make a container from birch bark. You can even cook with animal skins. Just turn the skin flesh side up and mount it on a tripod, then using sticks drop hot rocks into the skin filled with water. I've even seen water boiled in a paper cup, but placing it close to the flames, but not close enough to burn.
Or, if you just want to cook meat, stick it on the end of a small branch and learn it toward the fire, after sticking the other end in the dirt or snow. Our, as shown above, use the rocks and log to position the meat near the flames. Cook on coals or near the flames, never on the flames as it will burn your food.
