Even though they may taste similar, jams and jellies are slightly different. Jam is made from sugar and whole or cut fruits while jelly is made with sugar and fruit juice. Jams and jellies are fruit preserves, which were made in Rome and Middle Eastern countries. In fact, the first known cookbook has a recipe for jam, according to the International Jelly and Preserve Association. The long histories of jams and jellies has resulted in many successful established companies that continue to produce the fruit preserves around the world.

One of the largest American jelly brands is Smucker's. The business was started by Jerome Smucker in 1897 in Ohio and has grown into a large corporation, with stock traded on The New York Stock Exchange. The first product the company produced was apple butter and expanded into jams and jelllies during the 1920's, according to the company web site. The company makes blueberry, grape, apricot and strawberry jams and jellies. All of Smucker's products are Kosher.

Max Polander and his wife started selling jams and jellies out of their vegetable store in Newark, New Jersey in the 1900's, according to the company web site. Today, the company produces jams, jellies and marmalades; its jellies are produced in grape, mint and currant; jams are available in apricot, strawberry and raspberry. Polander also makes sugar free products, which contain only 10 calories per serving, according to its web site. Polander states that all of the flavor in its products are derived from natural fruit.
