Weasley Rum Punch
3/4 oz berry shrub base
1 1/2 oz ginger liqueur (or ginger syrup if you want it to be a little less boozy)
3/4 oz black strap or other molasses-y rum
1 1/2 oz aged rum
2 oz seltzer
scant 1/8 oz homemade spice extract
2 dashes Bittermens Grapefruit bitters
Combine first three ingredients plus spice extract in a shaker full of ice, shaking well to combine. In an tall-ish glass, add two cubes of ice, dashing grapefruit bitters over the ice before pouring in rum mixture and topping with club soda.
It works as a Weasley because of both the "ginger" connotation and the color...it's pretty much a fiery red. I really like this drink's flavor, as it's an unusual take on the classic Planters Punch formula of 1 of sour, 2 of sweet, 3 of strong and 4 of weak, plus spice. The vinegar base of the shrub really works in a very subtle way, and the heat of the ginger plays with everything as well, as shrubs were traditionally topped with ginger beer. I like how the spices play with the smoky molasses nature of the rum, and the brightness of the grapefruit bitters really makes it all sing.
Now, as long as I don't get sued out of existence, I'll be happy! Ms Rowling, if you read this, please enjoy the drink as much as I enjoyed your books. (And please don't sue me!)
