Jam Sour recipe: how to balance a sour with jam

How does the jam change the drink?

Tart cherry and raspberry jams make a brighter drink, while apricot and peach create a rounder profile. Dense jam should be loosened with lemon juice before the other ingredients go into the shaker.

• Skip extra syrup when the jam is already very sweet.
• Fine-strain jam with noticeable seeds.
• Taste a small test serve when changing jams.

Is foam essential?

Egg white is optional. It changes texture and foam more than flavour. If you use it, shake once without ice and then with ice for a smoother head; without it, the drink still keeps its sour character.

The most common mistake

The common mistake is ignoring how much sugar the jam already contains. If the first taste feels heavy, add a few millilitres of lemon; if it is too sharp, add a small amount of jam and adjust gradually.
