I like to blanch and freeze garden tomatoes, putting them in one-quart plastic bage. Then, on a cold winter night I whizz them in the blender with some nice oil. (You have to use your judgment on how much juice to keep in.) Add optional flavors such as basil, black pepper or garlic powder. It makes an incredible salad dressing - the taste of summer.   

However, you need to eat by candlelight, because the red dressing looks funny on green lettuce.

I also make the beginning of tomato sauce by sauteing onion and garlic, adding sliced garden tomatoes, simmering for a while and freezing. This is not much more work than preserving the plain tomatoes, and it saves time and dirty dishes later on.

We husk our corn and put it on a pie plate with 2 T water. Nuke 4 mins in our very small microwave. It's safer than trying to take off corn husks with steam trapped inside. Modern varieties of corn stay sweet from field to market.
