Substitutions

- Sweet like honey. Swap sugar for ¾ cup honey for a richer taste.
- A tad less sweet. Use ¾ cup sugar instead of a full cup.
Variations
- Lemon Basil Syrup. Add ½ teaspoon lemon zest for a citrusy brightness.
- Vanilla Basil Syrup. Stir in ¼ teaspoon vanilla extract after straining for a warm, sweet twist.
- Spicy Basil Syrup. Add a pinch of red pepper flakes for subtle heat.
Storing and Freezing
- Fridge. Store in a sealed glass jar in the fridge for up to 2 weeks.
- Freezer. For longer storage, freeze in an ice cube tray for up to 3 months and thaw as needed.
Top tip
