What’s Key Lime Pie Made of?

Key lime pie is made of a handful of simple ingredients. This famous Florida pie is easy to make. It requires no baking if you use a ready made crust and don’t use eggs. The pie is named after the Key limes used to make the smooth and creamy pie.

Key Lime pie recipes vary but all are made of the following:

  • Fresh-squeezed (or bottled) Key lime juice 
  • Sweetened condensed milk

What makes Key lime pie so distinct is the type of lime used called the West Indian lime or Mexican lime. They are sour and would make your mouth pucker if it weren’t for the creamy condensed milk and whipped cream!

Why is it Called Key Lime Pie?

Key lime pies are named after the Key limes that are the signature ingredient in this classic, tropical pie. West Indian limes were introduced to the Florida Keys in 1838. They became naturalized and folks started referring to these citrus fruits as Key limes. 

A hurricane in 1926 wiped out commercial lime production in the Florida Keys, but the name for these limes still endures.

Key limes are a type of lime that are perfectly round, lighter green, and smaller than regular limes. They have a floral aroma and are more acidic than the more common oblong Persian limes. These limes are slightly bitter, slightly sweet, and have a more intense taste. 

Key lime pie originated in the remote Florida Keys in the early 19th century. It’s thought that condensed milk was used instead of milk because refrigeration wasn’t common in the island chain until the 1930s.
