Definition
Oleomargarine is the full, original name for what we commonly call margarine. It's a butter substitute made from vegetable oils or animal fats, created in the 19th century. The name emphasizes its oily composition compared to butter. Often, it was artificially colored to resemble butter more closely. Today, the term "oleomargarine" is rarely used, having been shortened to simply "margarine." Think of it as margarineβs official, slightly cumbersome title. π
