Chili oil is like setting a 15 minute timer for me. Ten minutes in, my gut starts making terrible noise, and five minutes later, there's no chili oil in my system anymore.
Tastes delicious! But I learned a long time ago that it's an ingredient I need to avoid whenever I'm eating while on the run. Err, on the go.
On the flip side, I never understood the "coffee makes you poop" meme, but it's apparently a similar biological reality for a lot of people.
