Dehydrate your tomato skins (when canning) and turn it into tomato powder! You can do this with your apple peels too! Add the powder to any kind of apple cake or pie, etc and taste the extra difference!
my mom does this-Cleaning fruit - fill sink with water, add 1 C. vinegar, mix. Add all fruit and soak for 10 minutes. Water will be dirty and fruit will sparkle with no wax or dirty film. Great for Berries too--keeps them from molding. I do this with strawberries and they last for weeks!
