Hopefully this doesnt make me sound too ignorant, but I find Indian food hits different to hot sauce. With Hot Sauce you are trying to condense down all the different elements into a single substance its why it works so well on fairly bland chicken or with chips etc. Indian cuisine is like a palate of different flavours, so instead of having to build sour notes in they can have pickles, for sweetness take some chutney or a Raita or Lassi. Means I can handle a subjectively hotter curry than hot sauce.
That's probably a dumb take but I find that to be the case, and the larger the group the greater variety of extras can be justified and shared which makes the whole thing even better. At a 4/10 WBS (white boy scale) I get a bit of colour, at a 6/10 WBS I would be fairly rosy and have some sweat going, at 9/10 WBS I am beet red and the sweat is flowing (and I will probably pay for it the next day).
I had the pleasure of attending a Nepali wedding a few years back and I found all the food on offer there very manageable. Also went to a neighbourhood BBQ where a group of lovely Chinese ladies from Heilongjiang had prepared some dishes from their home. When I mentioned the flavour was great but it felt like it was.lacking in heat I got an immediate invitation to her house (which I sadly never took up due to life being busy) so she could make my wife and I the version that's not been "Australianised" by removing most of the heat.
Anyway all of that is a very roundabout way of saying that for someone as picky as I am about a lot of traditionally English foods, I am glad I can give other cuisines a crack.
Down here in Tassie we seem pretty well stocked for water as well. My family will likely be reining in our showers once it stops raining and the tanks are no longer covering our needs though. Right now the more we use the less strain it puts on our storm water drains. We might lean on the landlord to upgrade to a solar hot water system at some stage so our showers are closer to genuinely free.
