1 oz absinthe
4 oz grapefruit juice
3-4 mint leaves
1/2 oz St. Germain
1 pinch salt
dash angostura bitters
Bruise the mint leaves. You can do this by dropping them into your glass (preferably a highball glass) and gently using a muddler, or you can put the leaf in the palm of one hand, and smack it hard (clap). The idea is to release the oils without tearing up the leaf.
Add a few large ice cubes to the glass and then stir all of the ingredients together (except the bitters). For the salt, use something light and flaky like Maldon. Or you can go with kosher salt, if you want a little more grit.
Because grapefruit juice can be very sweet, very sour, or very bitter, give it a taste. Too sweet? Add a dash of bitters. Too bitter or sour? Add a little more St. Germain, or check out our variation below.
Drink it. Or make it for friends and be lauded for your heroic good taste.
