bake bake bake.
bake everything son. turn as often as possible... if you preheat at 220 and turn them every 10 mins, prolly only need 20 mins.
but after you find the correct timing for the thickness, try turning 3x or 4x. BOOM! *(but try to minimise the time it take to open and turn, make it very quick, don't let it cool down for a minute while you talk to the missus)
and to correctly bake, you need a good, thick baking tray, foil and baking paper (aka wax paper)
