Notes
Lakanto, Swerve, or Erythritol. I stick to Lakanto and Swerve which are a 1:1 swap with traditional sugar. If using a different brand of Erythritol, keep in mind it's 70% as sweet as sugar, so you may need to add more to taste.
Traditionally, cosmos are made with cranberry juice, which is extremely high in sugar and carbs. Since cranberries aren’t easy (or tasty) to muddle, I opted for raspberries instead!
