Rosemary Reverie: A Rosemary Blackberry Gin Sour Recipe

My herb garden is absolutely exploding with rosemary right now. Throw in a pint of blackberries that needed to be used up ASAP, and you know I was about to make a cocktail.

Zero waste is a great excuse, not that I need one.

What happened next was pure magic— my Rosemary Reverie is basically what would happen if a fancy botanical garden and your favorite berry patch had a baby in cocktail form.

The herbaceous gin and rosemary create this gorgeous aromatic foundation, while the blackberries add just enough juicy sweetness to make you want another sip.

Lemon gives it a little citrus kick, while the egg white balances it all out into one smooth drink.

It’s grounded, floral, and just the right amount of fancy — especially when served with a rosemary sprig and a fresh berry garnish.

Rosemary Reverie Cocktail Recipe

Ingredients:

  • 2 oz gin
  • 0.5 oz fresh lemon juice
  • 0.75 oz rosemary simple syrup
  • 0.5 oz blackberry purée or muddled blackberries
  • Optional: 0.5 oz egg white or aquafaba (for that silky foam)

Garnish: Blackberry skewer + rosemary sprig

Optional upgrade: A mist of absinthe or dash of herbal bitters to deepen the flavor.

Instructions:

  1. If using egg white or aquafaba, start by combining all of your ingredients into your cocktail shaker and giving it a good dry shake (shake everything except ice) for about 15 seconds to build that frothy texture.
  2. Add ice to your shaker and shake again — hard — for 15–20 seconds until chilled and blended.
  3. Strain into a chilled coupe or rocks glass.
  4. Garnish with a rosemary sprig and a skewer of fresh blackberries.

For an added twist: Gently clap a rosemary sprig between your hands to release its aroma before garnishing.

  • 0.5 oz rosemary simple syrup
  • 0.5 oz blackberry puree (or muddled blackberries)
  • 2 oz cold still or berry sparkling water
  • Optional: 0.5 oz aquafaba for foam

Garnish: Blackberry skewer + rosemary sprig

Instructions:

  1. Muddle the blackberries with the syrup and lemon juice.
  2. Add aquafaba if using, and shake without ice for about 15 seconds.
  3. Add ice and shake again until chilled.
  4. Strain into a coupe or rocks glass over fresh ice.
