2. Mix Ingredients: In a cocktail shaker, combine the sotol, apple syrup, espresso, and evaporated milk.
3. Shake: Add ice cubes to the shaker if you prefer your Carajillo chilled. Shake vigorously for about 15-20 seconds until well mixed and chilled.
4. Serve: Strain the mixture into a glass. You can serve it over ice cubes if you want it cold, or without ice if you prefer it warm.
