Because it is mostly peanut butter, it is a very special treat for all birds. We have grosbeaks, orioles, woodpeckers, sparrows, warblers and chickadees that love eating these cakes. Even the hummingbirds come by on occasion for a taste test. Of course, the chipmunks and squirrels also love the peanut butter cakes.
Place prepared tomatoes in a saucepan and cover with water. Heat to a boil and boil gently for 5 minutes. Add lemon juice or citric acid to canning jars along with 1/2 teaspoon salt to each quart jar, if desired. Pack hot jars with hot prepared tomatoes and fill with boiling water leaving -inch head space.
Unopened canned tomatoes should be used within six months. Once opened, store canned tomatoes in a covered glass container in the refrigerator up to one week. Leftover tomato paste and sauce can be frozen for up to two months. Freeze one tablespoon of tomato paste in each section of an ice tray, pop out when frozen, and seal in an airtight baggie for quick, pre-measured additions to soups and sauces. They need not be thawed prior to adding to your recipes in most cases.
