Raw "Crispy" crackers?

[Minnie]

I was making crispy crackers on tinfoil and teflex, but when I changed to parchment paper they became more stiff and less crispy. :eek:

Is tinfoil okay to use? Because I donÂ’t have square teflex and I need the square shape to cut for my potluck crackers coming up very soon. If tinfoil is not okay, why? And why does the parchment make them less airy and crispy? :confused:

Also I would like to buy 14x14 teflex sheets but so far they seem to be really high priced like $7.50 for one. I need 8 so thatÂ’s $60 plus tax and shipping. Does anyone know where to get cheap teflex. IÂ’m even willing to get used or smaller ones. Thanks. :p

Minnie :D

Tinfoil (aluminum in general) has a reputation of causing Alzheimer's Disease. I would not use it. Even underarm deoderant has it, use the natural ones. Teflex is expensive, but worth the price! ;)

I am not aware of any tinfoil being sold in this country, except perhaps for something used for craft projects. Not even sure that stuff is tin. Aluminum foil is often used for food things. Perhaps you were somehow linking the excess aluminum found in the brains of Alzheimer's victims to the use of aluminum products. Alas, this is a flawed theory. There is no proof that using aluminum causes Alzheimers. Foil is not advised for use with foods like tomatoes because they cause a reaction to it and can eat little holes in it.

I can't answer the question about the use of foil in dehydrators though. I did a quick search though and found some answers at this link:

It says aluminum is not advised because it can discolor the food. And futher down it says that foil used inside the dehydrator can increase the temperature and speed dehydrating. So while it might actually work, it might also raise the temp. high enough to where the finished product would not be considered raw.
