My BFF loves whiskey sours and comes over to my place often so I started batching them for her :)

3 parts bourbon 2 parts fresh lemon juice 1 part simple syrup (I used lavender for this batch)

Mix all, pour 5oz per container and freeze. Pull a couple out when she says she's on her way over, and 1 egg white per drink, dry shake, wet shake, serve up in a coupe. Enjoy ????
