Egg white fans,
Had a bunch of egg whites after making Creme brûlée for Christmas, so...
2oz cacacha (tequila, rum, mezcal, pisco would all work great), tablespoon orange marmalade, splash of agave syrup, small lime juiced (maybe 3/4oz), 1oz egg white, orange bitters
And then a similar looking but very different tasting cocktail. This is a really great wintry holiday drink. 2oz bourbon, 1/2oz maple syrup, small lime juiced (would have used lemon if I had some), 1oz egg white, orange and Ango bitters, grated cinnamon and nutmeg
