Alas, mulberry season is over. We had enough to make a sweet cocktail, but the yogurt mulberry cake will have to wait til next year. You could easily substitute blackberries.
I made a mulberry simple syrup by adding about a cup of mulberries to one cup water + one cup sugar, simmering until the berries broke down, then straining. As you can imagine, do not wear white while preparing or drinking these cocktails.
1.5 oz gin
1 oz mulberry simple syrup
0.5 oz fresh lemon juice
6 mint leaves per drink, along with a few berries
Seltzer or sparkling water
Muddle berries/mint. Fill glass with ice. Add remaining ingredients and stir. Top with some seltzer.
