Sometimes the best dessert is one that can both be delicious and refreshing. Which is why this time, we will be making a Key lime pie. We will make everything from scratch, from the graham cracker crust to its soft, Key lime filling.

ORIGIN OF THE KEY LIME PIE

The Key lime pie originated from the United States, mainly from the state of Florida. Although smaller than regular limes, Key limes are popular in Florida, being more aromatic and sweeter than regular limes. As of the 1950s, it became Florida’s famous dessert, and by 2006 it became Florida’s state dessert.

ASSEMBLING THE KEY LIME PIE

Graham crackers are usually made with a combination of all-purpose flour with whole wheat flour, giving it a more grainy taste. Graham crackers are also known for their strong honey aroma and taste. It’s dry, but when combined with melted butter, it will hold its shape but still be delicious and crispy.

As for the filling, it will be a custard filling, meaning it’s egg-based. But instead of the whole egg, we will be using just the yolk. And since we will only be using the yolk, the colour of the pie filling will be more of a light yellow instead of green like a lime. Don't worry, it’ll still taste like lime! It will then be combined with Key lime juice, condensed milk and Key lime zest. So the sweetness will come from the condensed milk.

Finally, it will be topped with some fresh, whipped cream and lime zest on top.

SERVING THE KEY LIME PIE

Key lime pies are best served cold. The freshness of the Key lime filling is best when cold. You will need to slice this with a knife dipped in hot water to be able to get clean cuts.

It’s a great dessert to have on a hot day especially living in a tropical country, so try these out for yourselves!

Some tips that might be useful:

  • When making the crust, make sure to pat it down tightly to preserve the structure.
  • Letting the pie set for 24 hours gives the best results for structure and taste.
