Made a batch of "Sorta Secret Aardvark Sauce" from http://forums.egullet.org/topic/128657-sorta-secret-aardvark-sauce-habenero-hot-sauce/ last week, it came out pretty good! Not quite the same as Secret Aardvark sauce but still tasty. I ended up using only half the amount of rice vinegar, and it definitely did not come out too thick.
Next time, I want to try it without the curry powder since I think that's what's contributing most to the difference in taste. I also want to add a little citric acid and xanthan gum.
