A dilemma - singular or plural verb?

Question

Which sentence is correct:

My favourite food are chips

My favourite food is chips

Answer 1

Food is a singular (collective) noun, so "is" is correct.

. . .at least that's what they taught us in the 4th grade

. . .but later I heard that it might depend on what your defintion of "is" is

That's why I am glad Bill Clinton was not my English teacher. :) - Netjert, Dec 28, 2011
