Margarine

Margarine (i/ˈmɑrdʒərɨn/, /ˈmɑrɡərɨn/, /ˈmɑrdʒrɨn/, or /ˈmɑrdʒəriːn/) is a semi-solid emulsion composed mainly of vegetable fats and water. While butter is derived from milk fat, margarine is mainly derived from plant oils and fats and may contain some skimmed milk. In some locales it is colloquially referred to as oleo, short for oleomargarine.
