Pound cake For instance, baking soda or baking powder may be incorporated to induce leavening during baking, resulting in a less dense pound cake. A cooking oil (typically a vegetable oil) is sometimes substituted for some or all of the butter, which is intended to produce a moister cake. Sour cream pound cake is a popular variation in the United States, which involves the substitution of sour cream for some of the butter, which also is intended to produce a moister cake with a tangy flavor. Some of these variations may drastically change the texture and flavor of the pound cake, but
Vegetable oil is increasing. The NNFCC estimate that the total net greenhouse gas savings when using vegetable oils in place of fossil fuel-based alternatives for fuel production, range from 18 to 100%. The production process of vegetable oil involves the removal of oil from plant components, typically seeds. This can be done via mechanical extraction using an oil mill or chemical extraction using a solvent. The extracted oil can then be purified and, if required, refined or chemically altered. Oils can be removed via mechanical extraction, termed "crushing" or "pressing." This method is typically used to produce the more traditional oils (e.g.,
