I've lived in several midwest states (Minnesota, Wisconsin, and Michigan), and while the midwest isn't known for spicy food, in these states I've always ordered the hot salsa for my burrito bowl when I go to Chipotle.
I'm in California now and just grabbed my first Chipotle here, getting the hot salsa as usual. However, the hot salsa feels significantly hotter than the hot salsa from the midwest - I've already downed my 16 oz water and I'm only half-way through my burrito bowl. Normally I can eat my whole burrito bowl without water (and yes, I know eating any food without water is unusual).
I know California has a higher proportion of Mexican restaurants than the midwest, and therefore it has spicier food on average. So I'm wondering if anyone knows -
Does Chipotle make the hot salsa hotter in states that have spicier food, like California, Arizona, New Mexico, and Texas?
That seems like it would make sense since the people in these states would have a higher threshold for spicy foods and might want some extra kick compared to midwestern people.
