Oh, boy the baggies! When I was growing up in Mexico you’d get a soft drink poured into a baggie tied off with a straw on the boardwalks. iirc it was so they could redeem the bottles. I forgot that was a thing. Cool to see it’s still around.

Sounds delicious. I enjoyed the inventor’s joke that the drink is served in a plastic bag, meant to optimize sipping while driving.

I made these tonight! I had to use fresh tomato juice instead of sangrita, but I think I accurately captured the salty sweet quality. Served to people who don’t like mixed drinks and they liked it.
