On a recent Friday night, my husband, Mike, discovered a carton of ripe blackberries shoved to the back of our crowded fridge. As a food scientist, he enjoys a challenging experiment. As a mixologist, he loves creating low-carb versions of classic cocktails. Eureka! His keto version of blackberry sidecars was born, using no added sweetener or Cointreau. They’re both visually stunning and with a delicious flavor profile that includes just a touch of sweetness – perfect for a romantic night at home.

Blackberry Sidecars Keto Friendly Drinks


Traditional sidecars contain only 3 ingredients: Cognac, orange liqueur, and fresh lemon juice. Popular in the 1920’s, sidecars have remained a classic cocktail for a century. Today’s bartenders often add sweeteners like agave nectar or simple syrup to these drinks, jacking up the carb count. A typical blackberry sidecar can run between 14 to 28 net carbs per serving. We reduced the net carbs down to 6!



Using blackberry vodka, blackberry brandy, and fresh lime juice, Mike created a low-carb blackberry sidecar that takes less than 5 minutes to make. Fill a cocktail shaker with ice cubes, pour in blackberry vodka, blackberry brandy, and fresh lime juice. Shake for 30 seconds, pour into  and enjoy these glamorous cocktails They’re the perfect blackberry sidecar cocktail – not too sweet, not too tart. They are traditionally served in a martini glass, which adds a touch of sophistication, but not always practical, as I’m a notorious spiller. The good news: They taste the same in plastic cups.

Each drink contains 1.5 shots of liquor instead of the typical 1 shot per cocktail. These taste so good, you’ll forget they can pack a wallop, so remember if you’re following a low-carb or keto diet, your alcohol tolerance levels are lower.

Before squeezing a fresh lime, cut a lime twist for garnish from the peel. My favorite tool for making the perfect citrus twist is a channel knife. They’re inexpensive and easy to use. Place the knife against the skin of the fruit and twist the citrus fruit, not the knife. A potato peeler will produce a thicker slice, but still does the trick. Add a couple of fresh blackberries for garnish if desired.

We love the ratio of sweet to tart in this cocktail. If you prefer a sweeter taste, sprinkle truvia to taste into the shaker.
