Raisin cake grapes." Some recipes in the United States circa the early 1900s utilized lard as an ingredient, which could be used instead of butter. Boiled raisin cake is a type of raisin cake whereby various ingredients are first boiled, after which the batter is placed in cake pans then baked. It is sometimes prepared with the omission of some standard cake ingredients, such as butter, eggs or milk. Boiled raisin cake may have a moist consistency. The cake dates back to the time of the American Civil War (1861–1865), when it was prepared in frontier areas using the Dutch oven. Basic
Vegetable oil Hydrogenated vegetable oils differ in two major ways from other oils which are equally saturated. During hydrogenation, it is easier for hydrogen to come into contact with the fatty acids on the end of the triglyceride, and less easy for them to come into contact with the center fatty acid. This makes the resulting fat more brittle than a tropical oil; soy margarines are less "spreadable". The other difference is that trans fatty acids (often called trans fat) are formed in the hydrogenation reactor, and may amount to as much as 40 percent by weight of a partially hydrogenated oil.
