I usually like to post recipes that are unique, because why would I give you a recipe for a key lime pie while there are thousands of recipes for key lime pies to be found on the internet? That would be a waste of my time, isn’t it?

Haha, well let me tell you. I post this recipe because sometimes I get a little upset. I get upset by all those key lime pie recipes out there that don’t use real key limes.

How can you make a key lime pie without using key limes? If you’re making a key lime pie without key limes than it’s just a lime pie in my opinion. So that’s why I’m posting a key lime pie. To tell you all about key limes and key lime pies.

All my knowledge comes from Wikipedia and Google. Wow how I love the internet 😉
Key lime pie is being made from “key limes”, which are special limes from Florida. Even in the rest of America they are difficult to find, I had to go to four (!) different stores to buy a bag of key limes. Key limes are much smaller than regular limes, they are about the size of a cherry tomato. The taste is different, of course it’s still a lime but they also taste more sweet and candy-like.

My heart breaks a little bit when I see a recipe for key lime pie which not even uses key lime juice and doesn’t mention anything about the origin of a key lime pie.

And then I’m not even talking about recipes on food blogs, but also on bigger recipe sites like Food Network.

This is what I read on Wikipedia: In 1965, Florida State Representative Bernie Papy, Jr., introduced legislation calling for a $100 fine to be levied against anyone advertising Key lime pie not made with Key limes. The bill did not pass.

Unfortunately, because that would have been fun! Can you imagine, they had to expand this bill to food blogs nowadays 😉

It was also through Wikipedia that I found this recipe for the ‘real’ key lime pie.

The story behind the cake is that there were a bunch of fishermen from Florida who went to sea and had to prepare their food without fire. They took cans of condensed milk with them (because of course they had no refrigerator and couldn’t bring real milk) and used that to make key lime pie. Nowadays the cake is baked in the oven for a few minutes just to set the yolks and distroy salmonella.

I also made the cake with a classic American graham cracker crust, it was my first time buying and using graham crackers! They don’t exist in the Netherlands but I think they are the same as ‘digestive’ cookies.

I you want to use regular limes to make this cake then you’ll need probably 4 limes. Did I tell how small key limes actually are? Phew… it took a while before I had enough juice squeezed out 😉

And if you use regular limes… please don’t call this a key lime pie but name it a ‘lime pie’ instead 😉 Thank you!

  1. i love key lime pie. looks great!

  2. I adore key lime pie! This recipe looks glorious! Plus, I couldn’t help but notice that you’re a Dutch girl! Love it–my grandparents emigrated from Holland in the ’20s =)

  3. Key limes haven’t been harvested commercially in the US since the 1930’s. Even of you do find key limes in the US, they’re from Mexico and referred to in the trade as… Mexican limes. They aren’t as rare as you might think, many large Mexican grocery stock them, as well as specialty food stores. Glad to see you’re not advocating bottled mystery juice, great for stripping paint or removing rust. Recipe looks great, cheers!
