How to peel tomatoes easily?
You don't want to boil them, you want to blanch them. This means you bring the water to a boil, cut a shallow cross into each tomato (scoring the peel), add the tomatoes (few enough compared to the amount of water that the water doesn't stop boiling) and let them boil for ~1 minute. Remove the tomatoes and dump them straight into ice water. Once cooled the peel should come right off.
