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.
Prune tomatoes to one or two vigorous stems by snapping off suckers (stems growing from where leaf stems meet the main stem) when they are 2 to 4 inches long. Tie stems to stake with soft string, twine or cloth, forming a figure-8 with the stem in one loop and the stake in the other.
