I think it would be cool to recreate this drink at home if you like Mountain Dew.
I am a big fan of margaritas, but I do not drink Mountain Dew.
However, I wouldnt be opposed to making one and trying it out.

Mountain Dew recipes are quite popular whether its with food, desserts, or beverages.
The bright yellow-green color from the Dew Garita looks very refreshing too.
Next, use the lime to get the sugar onto the rim of the cup.

Open pour the margarita into the glass, and top it off with Mountain Dew.
Serve with a straw.
Overall, this DEW Garita sounds super sweet from the soda and sugar rim.

I am more of salt on the rim bang out of girl too.
Plus, I think its unique that theres a margarita that uses Mountain Dew.
