A flat piece of paper is much more convenient to use than a paper sack in cooking, as it can be better fitted to the size of the article to be cooked. Wrap the article as a grocer wraps sugar, folding and refolding the two edges together until the package is of the proper size, then fasten with clips and proceed to close the ends in the same way. This avoids all pasted seams and makes the package airtight. - Contributed by J. J. A. Parker, Metamora, O.
