I feel I've had this drink before. It comes from this example being another one of those gin and apricot brandy recipes that keep coming back in different proportions. Also it is another one of a long line of Boston-named drinks like the Cooler, the Sidecar, and the Sour.
Just for kicks I used the distinguished Plymouth gin which is known as its own style of gin complete in itself. It's not London or Old Tom, but it's an old recipe that has been around since the Plymouth colony in Massachusetts began, or at least soon after. This is the gin of Plymouth, England and the industrious people who sailed from there to find a better life.
