The other day, while using Arabic flat bread in the sandwich maker to make sammiches for Herr Chaos and myself, I mentioned puff pastry as a possible alternative and today, while in the shop I got a roll to try it out.
The idea was to make it thin, for one reason or another, but practice showed that rolling it out may not be the best, as the dough does not raise as fluffy and dry as it is meant to. Another thing is not overfilling it with watery or melting stuff if you need the thing to stay crispy. Other than those two technical specifics, it works quite well. Baking time is about 5-7 minutes and I did not pre-heat. Pre-heating might be a good idea. Also, smear butter on the baking surface to avoid sticky situations.
Afterwards I had a look online and found a couple of mentions on that same approach, so I did discover hot water after all, but I guess it is only a matter of time before one tries to stick all possible kinds of dough in a sandwich maker.
