We love hot sauce so much that we have categories of favorites...LMAO!! I have a lot of the same as some of you guys already said.
Crystal, Red Rooster, Louisiana Hot Sauce - all classics for fried fish/chicken/cup o' noodles when I used to be addicted to them
Huy Fong Sriracha - in the squeeze bottle, love love love this stuff with rice, noodles, veggies, soups, meats, fish, anything really..my #1 or #2 favorite hot sauce of all time for sure (also any other sriracha rocks but this one is what I get)
Sambal Oelek - I grew up eating this w/the Indonesian food my dad cooked, it's hot as fire but when used in the right porportions really accentuates the dish (but I'm not kidding, the stuff is hot!)
Valentina - hot & extra hot flavors, my fave for burritos & quesadillas & I love it on ceviche/tostadas mixtas
Pico Pica - on tacos and on cheezits - omg!
Tapatio - different flavor & good for anything (I don't like Doritos but I'll eat them covered in Tapatio)
