Yes, you can. While we personally prefer using an egg white for optimum smoothness and foaminess, we know it's not for everyone. Though it's typically used in most foamy cocktails, there are a couple alternatives to raw egg whites that we've listed below: - Pasteurized Egg Whites: If you're not keen on using raw egg whites, the safer alternative is using pasteurized, bottled egg whites. We sometimes like to use this in place of raw ones to prevent wasting the egg yolks. You can use 2 oz in place of one large egg white. - Aquafaba: We've never used aquafaba (chickpea water) before, but it should give you that foaminess you're looking for. It's a great alternative for those that don't like eggs or are vegan. You can use 2 oz in place of a regular egg white.
