Shortened cakes, sugar cookies, pastry, biscuits, muffins, and yeast bread were made with oil in place of hydrogenated shortening with little change in quality. Either 1 c. or 3/4 c. oil could be subsituted for hydrogenated shortening in shortened cakes, biscuits, muffins, and yeast bread. Sugar cookies were best when 1 c. oil replaced 1 c. hydrogenated shortening. Pastry was best when 3/4 c. oil was substituted for 1 c. shortening. The effect of method of mixing on product quality often was greater than the effect of the amount of oil.
