This is serious. We’re not talking about the spice you get from mustard and ham sandwiches, pizza oil or an odd dash of wasabi. These restaurants have some of the most volcanic, stomach-troubling dishes in all of Sydney.

Of course, any amateur cook can blow your head off with a big handful of chopped chilli. A good spicy dish needs to have other things going for it than just intense heat – balance, texture and presentation, for starters. All our picks are nailing these things in their own way.

So if you're ready for the incendiary highs that come with chilli feasts, here’s where to go for Sichuan hot pot, Thai noodle soups, hot wings, Pakistani chilli-laden curries and Korean fried-chicken.
