Purpose
Add an acid near service so its brightness remains perceptible in the finished dish.
Controls
Fakes removes the soup from heat before stirring in 10 g lemon juice or red wine vinegar. Taste after the main simmer because the broth has already concentrated.
Process
- Finish the soup cooking and take the pot off heat.
- Stir in the measured acid, taste, and serve with the raw olive-oil drizzle.
Failure Modes
