Pineapple Lavender Mint Spritzer (with Lavender Agave Simple Syrup)

Bring water to a boil in a small saucepan. Reduce heat to low; whisk in agave nectar until dissolved. Remove from heat.

Stir lavender blossoms into the saucepan. Let syrup steep, about 15 minutes. Strain into a bowl through a strainer lined with cheesecloth.

Refrigerate syrup until chilled, at least 2 hours.

Pour 1 1/2 cup syrup into a glass measuring cup. Add mint leaves; mash gently with a cocktail muddler. Mix in pineapple juice.

Fill a pitcher with ice. Pour in pineapple juice mixture. Top off with club soda and stir. Serve garnished with a slice of lime and sprig of mint.
