English has hot, spicy and piquant.
Perhaps the lack of a dedicated mapping to "capsaicin sensation" stems historically from England's reputedly bland cuisine...
Thank goodness for immigration.
But I don't think it's fair to call UK food bland. Done properly it's very good, but what it's not (usually) is heavily seasoned. In no way does that require it to be tasteless, and done properly it isn't.
There is a reason there are thousands of Indian restuarants in England and approximately zero English restaurants in India. ;0)
Thankfully, food has improved vastly in the UK since the 70s.
England's bland food is a relatively recent development, much more recent than the language.
