Classic Key Lime Pie; Creamy, tart and sweet in a crisp graham cracker crust that's mildly flavored with a little shredded coconut, coconut oil and a touch of salt. The coconut gets nice and toasted while the crust pre-bakes!
Make graham cracker crumbs in chopper, food processor or blender. Add coconut, sugar and salt - mix until combined. Add coconut oil and mix until the texture of damp sand.
Spray regular (not deep dish) 9-inch pie plate with non-stick spray. Add crumb mixture to pie plate. Use a flat bottomed measuring cup to press the crumbs evenly across the bottom and up the sides of the pie plate. (see video in article for visual)
Bake crust for 10 minutes, the remove to cooking rack to cool. Leave oven set to 350 degrees F. (It's okay to pour filling into warm crust.)
Make Filling:
Combine egg yolks, and lime zest in mixing bowl and mix to combine. Mix in sweetened condensed milk. Then mix in lime juice and sour cream. Mix until just combined (you don't want it full of bubbles.)
Pour filling into crust and bake for 12 - 15 minutes. When it's done baking the center will still be jiggly and there will be tiny bubble around the edge. (It shouldn't brown on the top.)
Remove to cooling rack to cool completely, then chill in refrigerator for at least 3 hours or overnight. (The filling will firm up during this cooling/chilling time.)
To Serve:
Let sit out for at least 20-30 minutes at room temperature before serving. (It's much easier to cut and remove from pie plate once the crust warms up a little.) If desired serve with a little whipped cream!
Notes
Don't Like Coconut?
I never used to either, but I do like this mild toasted coconut flavor. You can totally skip the coconut too! Just replace the coconut oil with melted butter (use either unsalted or if you use salted - skip the salt in the recipe) and replace the 1/3 cup flaked coconut with 1/4 cup additional graham cracker crumbs.
Lime Zest:
When zesting limes, use a very fine rasp style zester (such as a Microplane). You want the finest/thinnest pieces of zest. When zesting limes, you only want to cut off the very outer green part of the skin. Only run the zester over a section of the lime one time, so you don't get the bitter white pith of the skin.
Key Lime Juice:
You'll need a bag or about a pound of key limes to make 1/2 cup juice (it'll probably make more than that, just depends how juicy they are.)
Regular Lime Juice:
When I can't find key limes, I use a combination of lemon and regular (Persian) limes. Juice 1 lemon into your measuring cup, then juice limes until you get 1/2 cup. (I usually use 1 lemon and 3-4 limes.)
Bottled Lime Juice:
I haven't used this myself - I prefer fresh if possible. (I have read that some folks like the Nellie and Joe's brand.)
