Old stand by: Dave's Total Insanity Sauce
New Fave: Moore's Habanero Sauce
Local (to Buffalo) Fave: Krista's Hot Sauce
When we're back in town, we always stop at the Tops in EA on our way out and load up on Krista's and Dave's - Can't find either here in PA.
And i do love Tabasco - has a great, tangy flavor.
Hottest I've ever tried: The Vontae Davis Sauce at O'Neills at Abbot & Soutwestern - That messed up my plumbing for a couple days.
