So it has come to my attention that some folks may not know how to do this.
Remember to not cut the bad spots out, if there are any, until after splitting the skins.
Start by cutting an X into the bottom of each tomato.
Toss a bunch into a pot of boiling water. Don’t overcrowd the pan. The tomatoes will rise to the top and roll around a bit.
After about a minute the skin will split on the tomatoes. Scoop them out when this happens and place in a large bowl to cool.
Once all the tomatoes have split and are removed from the pan, wait until they are cool enough to handle.
Grab the skins and pull them away from the flesh. Repeat until all are stripped. Cut any bad spots or bruises off now as well. From here the tomatoes can be canned, cooked or stored in the refrigerator.
