If you are lazy like me sometimes, when you grow tomatoes and you have too many and don't feel like doing anything with them at the time, did you know you can wash them, dry them off, take off the stem cut out any black spots and throw them in a ziplock bag whole, then freeze. When you want to make sauce out of them, you can thaw them a little and drop them in hot water to take skins off. Or, you could just blend them all up when thawed and incorporate the peels into the sauce. This does take up some space in your freezer if you have a lot of tomatoes but when laziness hits, have to do what we have to do!
