Substitute Mint with dried lavender or use 1 tbsp lavender and 1 tbsp mint. To do this, powder the lavender in a spice grinder before adding to the recipe, OR simmer lavender petals in the seltzer water for 15-20 minutes, then strain, throw away the petals and proceed with recipe. Strawberry, orange and lime flavored seltzer all work well Make a large batch as this will keep in the freezer for up to two months if covered. *This is based on the Trim Healthy Mama stevia brand that I personally use and linked to in the recipe which is quite concentrated. Stevia potency really varies from brand to brand so you may need to adjust the level of stevia to more or less depending on which one you use. Macros listed are for SP version.
