I had made salsa this summer (inspired by you and turbo in the Food Thread) that ended up pretty wimpy, so I got a bunch of habanero peppers and roasted them and added them to it! I like spicy food, but that was above and beyond what I could tolerate. A few bites and I thought I was on fire. I ended up having to cheat and add tomato paste to it to cut the heat to tolerable levels, which defeated the purpose of fresh salsa.

I had a bit of the "stock" batch left though, and just made guacamole with it (it's my cheater version of guacamole where I just add salsa to avocado and mash it all together)...now that was tasty guacamole! I regretted it a bit the next day, but that was just the way to deal with the heat.
Anyway, yeah, habaneros will definitely clear up any sinus troubles!
And...*cough*...I repeat in case Zz didn't hear the first time...I think I feel a sniffle coming on.
