Raw onions, fill your burger/burrito to the limit, hit it with habenero based hotsauce. Add coleslaw, and pork and beans for consistency, corn on the cob for tracers. Stand back and collect some ice for your tater, cause the eruption will be something to behold! You will wanna bronze that baby!
PBR
Caution NEVER, repeat NEVER, use the above with cheap chinese(MSG) airport food, the batter eruption is uncontrollable and will spatter everything within an arms reach, including your junk(backsplash), wiping off said junk is messy and embarrassing to boot!
I crop-dusted some pax recently on my way to the back not to long ago...boy did I get some looks on the return walk....
