I'm having a lot of problems with my waffles sticking to the iron. We've just bought a nice new waffle iron and 8 times out of 10 they stick so badly you can't make any more until the plates have been soaked and cleaned. I grease the plates with a silicone pastry brush and canola oil and clean them really throughly in between uses (the plates are removable).
Does anyone have any great tips for getting them to not stick and then split? Does the waffle recipe itself make much difference?
