One option might be to use a thin visquene sheet as your cook tarp and pack it into your bear canister if you're in bear canister area, or in your food bag otherwise. Also, if you use "freezer bag" cooking the odor level of your food will be minimized. Avoid strongly smelling foods, condiments, toothpaste, soap, perfume, etc. as bears will be attracted to these unfamiliar scents. I don't carry beef jerky or fish jerky with me even when I day hike here in summer.
