U.S.-grade powder food coloring by Elizabeth Parvu, instructor of cake decorating, judge on cake shows and owner of Sugarpaste LLC.

This 2-ounce container is preferred by professionals not only for its gram amount of powder (in any color) contrasted with the 2.75 grams of the smaller jar, but also for the larger container's shelf life--3 to 5 times the length of the smaller jars.

To compare the size of this jar with the size of the 2.75-gram jar, measure the smaller one. The larger one's dimensions: Lid diameter 2-1/8 inch, height of jar including lid 1-7/8 inch.
