Paul Hollywood: Easy Key Lime Pie

easy key lime pie

Paul says,

“No other dessert says Florida more than Key lime pie. I love the biscuit base, the smooth, creamy topping, and the tangy flavor from the Key limes. I worked my way through a few slices whilst in Miami–some were too sweet, others too sharp. This recipe strikes the perfect balance. You don’t need the small Key limes to make it; regular limes work just as well.”

Key Lime Pie Traditional Ingredients

The traditional key lime pie filling contains key lime juice, sweetened, condensed milk, and egg yolks.

A funny thing happens when you combine lime juice and sweetened condensed milk. It sort of “cooks” itself without any heat. The eggs, I’m told, add extra body to the mix, and by the way, give key lime pie its traditional yellow color.

A Little Key Lime Pie History

The Key lime pie has been traced back to the early 20th century in the Key West, Florida area and was invented by botanist Jack Simons. Its exact origins are unknown, but the first formal mention of Key lime pie as a recipe may have been made by William Curry, a ship salvager, and Key West’s first millionaire; his cook, “Aunt Sally”, made the pie for him.

It’s Soooo Easy

This pie is so easy to make, just five ingredients. If you can’t get key limes, you can use any tart lime. However, you can buy bottled key lime juice and sister it with a whole fresh lime. Only you would know the difference. Plus, it’s easier.
