Everyone knows the Huy Fong, and it's good... but if you see it you should get some Shark strong sriracha and give a try.
I get El Yucateco at my Mexican grocery. I think there is the 6 gift pack you can probably find online somewhere with all the flavors ,the 4 pack is easy to find for sure but it dosen't have the Caribbean one which is super amazing for wings, the Jalapeno sauce is not a big deal to miss.
