A bag according to claim 11 wherein said edible powder is flour.
Claim 15
Dependent Claim 140 words
A process of preparing an article of food comprising the steps of: providing an empty container comprising flexible sheet material resistant to temperatures exceeding 325*F.; introducing into the interior of said container a small quantity of an edible powder that at a cooking temperature of 325*F. is solid and insoluble in water; distributing said edible powder over the interior surfaces of said container, so as to minimize danger of eruptions during subsequent cooking of said article of food in said container; introducing said article of food into said container having said edible powder distributed over its interior surfaces; disposing said container and said food in an oven; maintaining said oven at an elevated temperature and at substantially atmospheric pressure, thereby heating and cooking said article of food; and removing said container and said cooked article of food from said oven.
Claim 16
Dependent Claim 140 words
A process of preparing an article of food comprising the steps of: providing an empty container comprising flexible sheet material resistant to temperatures exceeding 325*F.; introducing into the interior of said container a small quantity of an edible powder that at a cooking temperature of 325*F. is solid and insoluble in water; distributing said edible powder over the interior surfaces of said container, so as to minimize danger of eruptions during subsequent cooking of said article of food in said container; introducing said article of food into said container having said edible powder distributed over its interior surfaces; disposing said container and said food in an oven; maintaining said oven at an elevated temperature and at substantially atmospheric pressure, thereby heating and cooking said article of food; and removing said container and said cooked article of food from said oven.
