Not 2 cook but t melt the glue, recommended minutes?

20 min on gas mark 3 and leave to stand for 3 min ..then enjoy

why dont you just ceap a look at them till the glue melts

Make dam sure they are up to room temp before you put them in the oven -i.e not straight off the car into the oven

also a hair dryer works better and there's less change of cracking because you can control the heat and concentrate it on the glue

wait until they're golden brown mate, remember to turn them half way through though

I'd try the dishwasher first, that'll get them hot and it'll even clean them.

If you keep openning the door they won't rise properly.
