Why don't people in Europe have key lime pie?

Key lime pie is a traditional dessert that originated in the Florida Keys in the United States, and it is made with key lime juice, sweetened condensed milk, and a graham cracker crust. While key lime pie has become a popular dessert in many parts of the United States, it is not as widely available in Europe.

There are a few possible reasons why key lime pie is not as popular in Europe. One reason is that key limes, which are smaller and more acidic than regular limes, are not commonly grown or available in Europe. As a result, it may be more difficult and expensive to source key lime juice and other ingredients needed to make the pie.

Another reason is that different regions have their own traditional desserts, and key lime pie may not be as well-known or established in European cuisine. For example, in France, tarte au citron (lemon tart) is a popular dessert that is similar in some ways to key lime pie, but uses different ingredients and has a different flavor profile.

It's also worth noting that taste preferences can vary widely between cultures, and what is considered a popular dessert in one region may not be as well-received in another.
