(Sorry for the mixed measurements - I had a bunch of egg white so had to weigh out 1 egg worth)
35 grams egg white
1 Tbsp guava jelly or guava paste
1 oz good mezcal
1/2 oz over proof reposado tequila
1/2 oz Aperol
3/4 oz lemon juice
ETA I failed to list one step. First: whisk or muddle the jelly and booze to incorporate it.
Shake without ice, then with ice. Just as good as it sounds and so beautiful.
