Sugar-Free Keto Lemonade Three Ways

Is anything quite as sweet as a cup of cold lemonade on a hot day? This Keto Lemonade recipe is even sweeter because it’s made no added sugar. Taste and adjust as you go until you get just the right tart-to-sweet ratio. This lemonade is great on its own, but we’ve also included two delicious riffs: Basil Lemonade and Smashed Raspberry. Yum. Make sure to let the lemonade sit in the fridge while the flavors marinate together before serving.
