I like to get out a drink tumbler and a muddler and muddle together the limes, stevia and mint in the bottom of the tumbler. You can also do this in the bottom of your glass.
Add the muddled mixture to your glass, add ice and la Croix and mix in the tumbler and then pour over into your glass. I like to mix it back and forth a bit between the tumbler and your glass, there is no wrong way!
Make it pretty for yourself and garnish with lime wedge and a sprig of mint! Enjoy.
