As for the sweetener, my children prefer organic cane sugar but they will happily drink it with Stevia or Erythritol. I choose products like stevia or erythritol from Pyure to keep my carb count down.
Pink lemons will give you a beautiful light pink drink, however if you want a pinker drink, try adding 1/4 - 1/2 teaspoon of pure beet root powder. This can be found in the bulk spice sections of many health food shops. Locally, I get ours from Three Rivers Market.
If you can't find Pink Lemons just use regular lemons and add more beetroot powder!
