Key Lime Pie: with Salty Sweet Pretzel Crust

Key lime pie is a great summer dessert recipe and so easy & delicious to make. It’s made with a buttery sweet salty pretzel crust which is the perfect counterpart to the sweet tart custard like filling.

It requires just a few simple ingredients but the results look like it came out of a 5 star restaurant. A light and citrusy summer desert that cleanses the palate.

Theres 4 things the summer brings to south Florida. Heat, humidity, hurricanes & key limes. This recipe contains limes that came from Coral Gables, Florida.

Who knew key lime pie had a history & controversy surrounding it? Just about every food or ingredient we eat has a history attached to it. Call me weird, but I love learning about the history and origins of food.

Things you might not know about key lime pie:

1. It’s the official pie of the state of Florida.
2. A key lime pie is yellow not green. The egg yolks give key lime pie its yellow color.
3. Key limes are much smaller than Persian limes. They also contain seeds and take on a yellow color when they fully ripen.
4. Key limes are in season in Florida from June through September.
5. Key limes are much more aromatic than Persian limes.
6. You can use Persian limes in a Key Lime pie, but if you have them around use them. You can also purchase Key Lime Juice.
7. Some people complain about how long it takes to squeeze key limes, but it didn’t take long at all and I probably used about 12-15 key limes to get 1/2 cup of juice for the recipe. You can also buy a citrus juicer to make things a bit easier on you.

Key Lime Pie History and Controversy:

Local key west legend has it that a woman named Aunt sally invented the key lime pie in the late 1800’s . She was allegedly a cook for Florida’s first self made millionaire named “Rich” Bill Curry and made the pie for him whenever she could. The pie is still made at the Curry mansion today.

Historians dispute this story as no actual record of Aunt Sally or her recipe concretely exist. They contend it was the sponge fisherman who invented the initial version of key lime pie.

They stayed out at sea for long periods of time and had rations of crackers, eggs, sugar, canned milk, and citrus fruit.

They would mix a concoction of sweetened condensed milk, sugar, and eggs and spread it on crackers for a meal because refrigeration didn’t exist and they couldn’t cook on the boat.

The acid in the egg actually coagulates & cooks the eggs. Some say the original pie wasn’t even cooked. 

Others believe the fisherman showed aunt sally this trick and she took that knowledge back to her kitchen and perfected the famous Key lime pie.

And the third and final dispute comes from a cookbook author who a few years back, stated that the key lime pie was invented by The Borden Co. as a riff of a lemon tart recipe in a cookbook in 1930’s in order to sell more sweetened condensed milk. 

Many believe sweetened condensed milk wasn’t around at the time Aunt Sally laid claim to her famous pie, but that my friends would be false.

Gail Bordon the owner of the Bordon Company invented sweetened condensed milk in the 1850’s which became very popular during and after the civil war.

The gov’t purchased and distributed sweetened condensed milk in large quantities for the Union soldiers as a way of feeding them on the field. 

So you see, sweetened condensed mils was around the time Aunt Sally would have used it in her recipe, and it is very possible Aunt Sally was a real person and invented the Key Lime pie.

And that my friends is good enough for me. I really don’t care who invented, I’m just glad someone did because I really love key lime pie.

This recipe has a salty sweet crust that goes perfectly with the tart sweet custard like filling. I hope you enjoy this recipe.
