In a medium saucepan, add sugar, water and dried lavender.
Cook over medium heat until boiling, without mixing. Reduce heat to low and simmer for 15-20 minutes.
Carefully, use a fine sieve to carefully sift out the lavender.
Optional: add 1 drop of purple food coloring for a more intense color. For a natural color, add a few butterfly pea flowers at the same time as the lavender, then add 1-2 teaspoons of lemon after straining the flowers out.
Cool down completely, then transfer into a clean and dry airtight jar or bottle. Store in the fridge for up to 2 weeks.
Notes
Quantity: this recipe makes around 1 cup of syrup or 6 servings.
Storage: use a clean airtight bottle or mason jar to store the syrup. Keep in the fridge for up to 2 weeks. If it crystallises, this is completely normal and can happen. Just cook again over medium heat until fully dissolved.
