The thing about a phall is that it's not, like, a real dish. It's the item they put on the menu for pricks who just want to be a hard man and "order the hottest thing on the menu". It's just an invitation for the chef to make you something inedible as a punishment for your hubris, but that also means it's not usually a very nice actual curry.

If you want a very hot curry that is still an actual tasty curry, vindaloo is generally your man.

Vindaloo is based loosely on a Goan dish of the same name, but like all of them the British version bares only a passing resemblance to its authentic relative (which really has more in common with the Bangladeshi style of cooking).
