Baked Key Lime Pie Recipe + How To Use a Citrus Squeezer

This Baked Key Lime Pie Recipe contains not only sweetened condensed milk and key limes, but also egg yolks and whipped egg whites.

This means two things. First, It must be baked. Second, the pie will be lighter in texture. Allow time for the pie to chill.

Key Lime Pie--Ready to eat

My sister Kay was just here from Alabama for a brief visit. She’s a good southern cook, so I’m always keen for her recipes. This time I coerced her into making her Key Lime Pie while I took pictures.

WHAT IS THE CORRECT WAY TO USE A CITRUS SQUEEZER?

Kay: “I’m not sure how would be the best way to juice these key limes.”

Me: “I’ve got one of those metal squeezy things…. or a reamer… or even a glass dish with a built-in reamer. Here, let’s try this metal lemon juicer.” (I pull it out of the drawer and proceed to try it.)

Me: “See? It works perfectly.”

Kay: “I see that, even though you’re doing it upside-down.”

Me: “What?!?! That’s not upside down. What do you mean? So how would you do it?”

Kay: “The other way, with the lime-half flipped over.”

Me: “Hm-m-m. I don’t know about that, but I have an idea. Why don’t we ask my readers?”

DOES THE LIME (OR LEMON) GO UP OR DOWN?

The cut side goes down.

how to squeeze a lime correctly? cut side up or down?

The verdict is in…

Looks like I was wrong on this one. Although a few people agreed with me, many more went with my sister. (Her way is shown on the left in the picture above–cut side down.)

I am generally an early-adopter. But on this one, it looks like I’m a little late learning how to squeeze a lime with a citrus squeezer. Thanks for straightening me out, Sis.

FAQ

How do you know when Baked Key Lime Pie is done?

When properly baked through, the pie will have a slight jiggle–like Jello. Remember that the pie will continue to bake for a few minutes after you remove it from the oven. If you over bake it, the texture will be spoiled with a curdled effect.

Can I substitute regular limes for key limes?

Yes. It takes 4-5 key limes for every regular or Persian lime.

What is the difference in the taste of key limes and Persian limes?

“Key limes, also known as Mexican or West Indian limes, are more aromatic, with tarter and more floral juice. They are slightly yellow in color and contain more seeds.”
TastingTable

How long does key lime pie last?

When refrigerated, key lime pie will last 2-3 days.

Can I use a regular pastry crust instead of a graham cracker crust?

Perhaps. I’ve never tried it. A graham cracker crust is the traditional way to serve key lime pie. I can’t imagine it any other way.

    Can't wait to try the recipe but was surprised to see that I've been using my citrus press incorrectly. The cut side should be facing down so the juice goes out the holes and doesn't squirt upwards. Plus, it turns the peel inside out, extracting every bit of juice.

    I adore cooking, but detest cleaning up, so the less mess I make the better. I clean as I cook so that by the time it's in the oven or on the stove the kitchen looks like I just started. If I don't do it that way, I get depressed. That's why I try to get cooking in as early in the day as possible. By 6PM, I'm ready to call it quits, so everything gets set up and cleaned up before then. I specialize in methods and recipes that require very little kitchen disruption.

    I vote for cut-side down because if you do it the other way it blocks the holes which are there for a reason-to let the juice drain out. Sometimes, depending on the size of the fruit, I will do it one way, flip it and do it again the other way just to get more juice. I even quarter grapefruit and squeeze it rather than drag out my electric juicer which would make me have an entire machine to wash.

    Henrietta, Grapefruit??? Why haven't I thought of quartering them like that? You are a genius. Can't wait to try it. pr

    As for the lime, I've always done it with the face up like on the right but on food network I've always seen them place them face down like on the left.
