In this recipe, we rise to the challenge of a personal favorite: Key Lime Pie. This is an easy, low commitment recipe (with the exception of a 4 hour chilling time) that yields a tangy punch of flavor and silky smooth texture. Seriously, who doesn’t like this cool, creamy treat?
Before we dig deep, did you know Key lime pie very specifically calls for Key limes? So-called, “Key limes” are grown in the Florida keys but limes aren’t native to Florida.
Key Lime History Lesson
Limes originated in Southeast Asia. They travelled with the early explorers until they found a home in the West Indies, Mexico and the Florida Keys.
Florida farmers planted crops of Mexican limes which later became known as Key limes. Plot twist; those crops were destroyed in a 1926 hurricane and were subsequently replaced by heartier Persian limes.
This is where it gets fun: in 1965, Florida State Representative Bernie Papy, Jr. introduced geographical indication legislation calling for a $100 fine to be levied against anyone advertising Key lime pie not made with Key limes. This is hilarious since Key limes aren’t native to Florida!
However, despite the bill failing, some people still get upset if you call it a Key lime pie without using Key limes. I think we’re so used to the name that calling it plain old lime pie just doesn’t sound right.
On July 1, 2006, the Florida House and Senate both passed legislation deeming “Key lime pie” the official Florida state pie. So, when in the state of Florida, don’t ask for a slice of their famous Southeast Asian lime pie.
In my kitchen, my Key lime pie can use any kind of lime and you can call it whatever you want.
Back To The Recipe
In addition to Key limes (or any limes), this recipe calls for a Graham cracker crust. Bucking with convention (because *gasp* I am seriously not a fan of Graham crackers),
The Twist:
I subbed in tea biscuits, namely, Social Tea Biscuits…I know, I’m an unhinged culinary rebel. Trust me on this, it’s sooo good.
