( safety & taste ) -- a few basic questions

it's very hard to find reliable sources

on the back of a tortilia, it says to microwave it and other ways to method

* is torilia made from 'corn' safe to eat without heating/cooking?


* how long do you have microwave 'franks' for it to be safe?


* does bread/flour, etc. actually taste -- significantly -- different to 90%+ of ppl?

they don't really taste that different


* is there any yummy sauces that most ( >70% ) ppl like very very much?

* is there any best sandwiches/subway recipes that most ( >70% ) ppl like very very much?

please link sources

What does this have to do with Japanese food & recipes?

I would also suggest reading the forum rules. There are communication standards on this forum for English and I can certainly see why in this case.
