About the Boston Sour
The egg white adds texture, not flavour: shaken hard, its proteins trap air and give the sour a silky foam. Shaking once without ice first, a 'dry shake', makes the foam thicker.
Missing something?
- No Bourbon? Use Jim Beam Bourbon (Jim Beam is a bourbon)
- No Bourbon? Use Jack Daniels (Tennessee whiskey is made much like bourbon)
- No Lemon Juice? Use Lemon (Squeeze fresh: 1 lemon gives about 30 ml)
- No Lemon Juice? Use Lime Juice (Sharper, different aroma)
- No Simple Syrup? Use Rich Simple Syrup (More concentrated, so use less)
- No Simple Syrup? Use Sugar (1 tsp sugar is about 7.5 ml syrup; stir until dissolved)
- No Egg White? Use Aquafaba (Chickpea Water) (Chickpea water: same foam and vegan. Use the same amount)
