I changed up a few things in the recipe and it completely changed the drink for the better. This time splitting between Mezcal and Tequila Reposado and muddling a couple slices of Serrano pepper to add a bit of a spice element which I love pairs with Mezcal as you know, and this time making the sour without egg white.
