I can all summer long and into the winter. I mostly do hot water bath but do have a pressure canner. Also, I normally do tomotoes and or salsa every year but other items I may not depending on what I have on hand.
So Far this year:
Apple Butter
Apple Sauce (Cinnamon and plain)
Apple Rings
Apple Pie Filling
Apple Pie in a jar (ice cream topping) (I have 3 apple trees)
Salsa
Tomatoes
Tomatoe Juice
Cucumber Rings
Pickle Relish
Bread & Butter Pickles
Spag Sauce (though I don't think it is worth the time)
Peach Pie Filling
Peaches
Beets
Pickled Beets
Potatoes
All kinds of jellies and jams (I make about 10 kinds total) Unless I can get a good deal on fresh fruit I use frozen. It usually comes out cheaper and I can make it any time of the year.
My MIL and I will can just about anything at least once. I hate to see good food go to waste.
Tomatoes are really easy. They just take time. Blanch, remove skins, chop (if desiered) add salt some lemon juice or citric acid and seal. (They will sometimes turn pink when they have been setting for a long time) When I was learning to can when I was younger my grandma started me on tomatoes. She told me that's what she learned with so that's what she started everyone on. If you are really interested I would recommend getting a Ball Blue Book. Even if you pick up an older copy I think it is well worth the information. USDA (I think) also is a good resource for canning information. They have a "cookbook" that you can print for free with all kinds of recipes for canning. My biggest fear is still making someone sick. When in doubt I will toss something rather than chance it.
