I first of all washed it front and back with warm soapy water, then I put it straight on a big gas burner and burnt all the coating off, the I wiped oil all over it.
Ive just used it and I made a right hash of the nan (could get it big round and flat and onto the tava all in one go) so I ended up with a big thick nan, however it tasted good and BIR like so next time I will make sure I roll out the nan on a floured surface first and get it ready.
There's certainly no problem cooking the back of the nan thats on the tava, it was very well done
