You can't use oil in pastry. You need solid shortening so that you have layers of fat and flour. That is what makes it flaky.
......................
Oil can be used in making pastry, but as has been said, the resulting pastry will not be flaky, but crumbly. One can temporarily thicken some types of oil (especially pure olive oil) by refrigerating it. But the oil warms and returns to liquid state so quickly that it is not possible to produce flaky pastry with it.
Canola oil would be in the vegetable group but some people would say it's not classified as a food really.
An Alimentary Pastry would be a nutritious pastry. Alimentary being a word that describes food or something related to nutrition.
Pastry named after a French general would be "Napoleon."
Too much gluten in the pastry causes the pastry to toughen. The end result of such a pastry would be a tougher pastry - less flake and tenderness. Prohibit the gluten formation by not using too much water. (water causes gluten to form) and in addition do not over work the pastry. The more the pastry is handled, the more gluten is formed, the tougher the pastry.
I would use Crisco instead. With it your pastry will be good.
You don't. Add not additives to your oil. If additives worked the manufactures would add them to the oil and recommend you also do so.
i would say its more of a pastry
That would normally be a baker.
Yes.
There can be additives, however if you grow your own (Now legal in many locations) then there would only be what you chose to put in it.
Most finer restaurants have pastry chefs, so any large city.
