Fill each glass with a few spoonfuls of the strawberry puree. Fill the glass with ice. Add 1 to 2 ounces of gin over the ice and stir it into the strawberry puree. Pour a few ounces of the strawberry juice in next, then finish filling the rest of the glass up with the lemonade. Garnish with a few lemon slices and strawberries. Add a straw and serve!
Blend together the strawberries and water until smooth and blended. Pour half of the mixture through a fine mesh sieve to strain any solids. You have your strawberry juice! Keep the other half of the puree to fill up the bottom of the glasses. This will leave you with extra, so you can store it in the fridge in a sealed container for a few days!
