What each ingredient does
- Flax seed
- Its mucilage thickens the water, giving the lemonade a light body and silky mouthfeel.
- Sugar
- Adds sweetness that balances the tartness of the lemon juice.
- Lemon juice
- Provides acidity and bright citrus flavour that cuts the sweetness.
The step that matters
Steeping the flax seed. Flax seed releases its thickening gum slowly into hot water. Steeping for the full time lets the mixture thicken properly; straining afterwards removes the seeds so the drink stays smooth.
