Lavender Lemonade

For the lavender simple syrup:
Add sugar, lavender and water to a small pot, mix well and place over the stove on low heat. Slowly bring to a boil, reduce heat and stir until sugar is dissolved. Remove from heat and allow lavender flowers to sit in the mixture for 2–4 hours, the longer the better. Strain lavender flowers from simple syrup after time has elapsed.

For the lemonade:
Add the batch of simple syrup, cold water and lemon concentrate to a large bowl or pitcher and mix well. At this point, you can put it in your freezer until it turns to slush before serving or, if you have an ice cream maker, use this to turn the lemonade into slush quickly.

Serve immediately and garnish glasses with lemon slices.
