I use unbleached Baking parchment from Tesco, and cut two dinner place sized circles out of it.
I make up one pack. Then I put four dollops (if thats a technical term!) at 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock positions. Then, using the back of a teaspoon, I work in a circular motion and spread them out gradually.
I then microwave them for 1 min 30 secs on high in a 900W microwave. This crisps them with only a little bit of brown on the outside crusts (which I quite like).
While that batch is cooking, I make up another 4 circles on the other bit of parchment paper. When the first lot is pinged, I pull them out, pop the other lot straight in and turn them on, then simply peel the done ones off onto a cooling rack. If you have mixture left, simply re-use your first bit of parchment, and make a few more when the others are pinged.
Doing it this way is quite quick, and you can get them all done in less than 5 minutes with no fuss or waiting around.
I can usually get about 10-12 decent sized crisps.
