The answer to the question about cooking on a grill is Barbecue. The answer you accept is a kind of quasi-abbreviation and it spoils this quiz. You should think up something starting with E, not Q for the next answer.
I never thought of it that way, but now that you mention it I can see why using the abbreviation would be so problematic. Thank you for the feedback! I've updated the quiz so that the sequence is more seamless. Let me know what you think!
