I don't read Greta Christina's wonderful blog for cocktail recipes any more than I follow Rachel Maddow for them... but the latter's occasional cocktail moments spurred my interest in mixology, and now the former has provided my latest favorite drink.
Taking a bit of a break from blogging to work on her forthcoming book, Greta had been reposting some older articles, and it was my (and everyone's) good luck that one of them was for the Half Century, a drink she'd devised a couple years before to celebrate her 50th birthday. The drink itself, which Greta describes as "roughly a whiskey sour made with lime juice and cardamom simple syrup," is straightforward:
go read Greta's post to get that recipe¹). It's awesomely good smelling to make, and awesomely delicious. It makes this a go-to whiskey drink and I can't wait to find new ways to use it!
¹ Be sure to read the comments for clarification on exactly what kind of cardamom you need and how to source it.
