Next up, try a Tindaloo or a Phal. Basically the Phal was invented in Birmingham for drunk English after a night out.
Tindaloo is a vindaloo with more chillies or chilli Powder
Phal is one of the hottest forms of curry regularly available, even hotter than the vindaloo, using a large number of ground standard chilli peppers, or a hotter type of chilli such as scotch bonnet or habanero.
