wash and uncap
boil just long enough to easily remove skins
set on a plate, tops down and slide the skins off
halve and cool
Adding a sprig of fresh basil before freezing locks in a fresh flavor. I use Big Mama Plum tomatoes and usually start them as seeds myself in recycled newspaper pots I also make. They are meaty and enormous and make beautiful sauces. There are minimal seeds in this type of tomato, so there's no need to remove the seeds, unless you really want to.
Today, I skinned and halved one bushel and expect to have another before the season it finished. Happy gardening!
