I eat clean, so personally wouldn't touch them. If I did, I'd eat them wherever the fuck I wanted. To hell with foods that can only be eaten at a certain time of day.
I don't think flour is that bad. I make my own pasta with flour, plus do a lot of other baking with flour. I eat clean, but if I want a treat I'll always try and make it myself rather than buying heavily processed stuff.
Shop bought crumpets are full of added chemicals that your body doesn't need. If you want crumpets, make them yourself.
Guaranteed they'll taste better than anything you can buy in a shop.
