What each ingredient does
- Linseed
- Its mucilage thickens the water and gives the tea a soft, slightly viscous body.
- Liquorice root
- Adds a sweet, earthy flavour that rounds out the tea.
- Lemon
- Its juice adds acidity and its rind adds bright aroma.
- Sugar
- Adds sweetness that balances the lemon's acidity.
