Difference Between Key Limes & Persian Limes

Key limes are smaller, contain more seeds, and have thinner skin than Persian (regular) limes. As key limes ripen, they turn a yellow hue and lose acidity. The juice takes on a sweeter flavor and has a unique aromatic flavor.

Since key limes are smaller, it takes about 5 key limes to equal the juice you will get from 1 regular lime.

Can You Substitute Regular Limes for Key Limes?

Yes! If you can’t find key limes, Persian limes will work. I know it technically won’t be a true key lime pie, but I promise no one will know. The flavor is still amazing!

You can also buy bottled key lime juice, but I don’t recommend it. The processing changes the flavor and it will give your pie an “off” taste.

How to Juice Limes

Here are a few tips to getting the most juice out of your limes.

  • Store limes in the refrigerator. Leaving them out on the counter hardens the rind and dries out the flesh. Plus, they will last longer in the fridge.
  • Let the limes come to room temperature before juicing.
  • Place the limes in the microwave and heat it for 15 seconds. Heating the fruit helps release its juices.
  • Before juicing, place your palm on a lime and roll it around on a countertop or hard surface. This separates the individual segments inside the lime, making the lime juicer.  
  • Use a citrus squeezer, one of my favorite kitchen tools, to juice the limes. Place the limes cut side down in the squeezer and squeeze away! Make sure you put a bowl underneath to catch the juice.

How to Make Graham Cracker Crust

How to Store

Key lime pie will keep for 2 to 3 days in the fridge, covered loosely with foil or plastic wrap. For presentation purposes and to keep things super fresh, we recommend waiting to top your pie with whipped cream until you are ready to serve it.

  37. Ooh I love key lime pie. I haven’t made it in a while though so it might be about time again.

    Happy belated birthday to Josh!

  38. I’ll have to try this Key Lime Pie recipe! I’ve been on the search for a great recipe and this looks like a winner!

  39. Saw this on Make&Takes and had to give it a try. I used a different crust (I was trying out a graham cracker from scratch — no packaged crackers– so the crust I made wasn’t exactly easy!); but the filling was awesome and totally redeemed my dinner last night! (I made an AWFUL calzone for my hubs, but) your dessert redeemed me!

    I will definitely be checking your website out more often.

    Thanks for the idea.

  40. I was born and raised in Key West…your key lime pie is authentic! (well except for your lime juice) So often the key lime pies you see outside of south Florida are crazy lime flavored concoctions that are not even close. Just wanted to tell you about Nellie and Joe’s Key Lime Juice. It’s bottled key lime juice that is all we Key Westers ever use. πŸ™‚

  41. I LOVE key lime pie, but I’ve found that anything made w/ sweetened condensed milk gives me such a sugar-crash it’s just not worth it. Anybody know of a recipe that uses cream or something instead?

  42. Why didn’t you just call this pie lime pie? Key limes are yellow and quite different. The term “Key lime” is misused so often

  43. I didn’t say the pie would not be great, I said that it was not Key Lime Pie, it is just plain old Lime Pie. some cooks actually color a lime pie green I guess because the skin of a lime is green, but when they color a pie they are calling Key Lime pie green they are really misrepresenting …key limes are yellow, inside and outsice

  44. YUM! Key lime pie πŸ™‚ looks delicious. Great to see you pie on PW’s website, my pie is there too πŸ™‚ how fun!

  45. Great recipe! I used this for a party with friends who like fruit pies best for dessert and it was a big hit! The extra zest was perfect, as I prefer a more tangy lime flavor. I would be interested to try it sometime with key limes to see if the flavor is any different. (By the way, my limes must be HUGE because I only had to use 2 to get a half cup of juice, not 5!)

  46. This pie looks beautiful. I’ve been looking for a pie recipe for Easter and I think I’ll try this one. Thanks.

  47. Just wanted to let you know that I made this pie for Easter as I said I would. It was fabulous! The only problem was that I didn’t bake 2 because everyone wanted more. Thanks for another great recipe!

  48. I’m back and making this today for Mother’s Day – also, yeah, I just “pinned” this. πŸ˜‰

  49. I’ve made this multiple times and it tastes even better the next day. Much stronger lime flavor! Love this recipe.

  50. This is the recipe I’ve been using for over 20 years and always get raves. A step-daughter requests it every time she visits. I sometimes use a regular crust and always top with real whipped cream!

  51. Any thoughts on how far ahead I can prepare this before serving? Β  Assuming it’s refrigerated is 48hrs too soon?!

  52. 5 stars
    The key lime pie recipe is a wonderful pie! Β Not only does it taste good, it is really simple to make. Β The only thing I would change is to garnish each piece with fresh made whipped cream (don’t tuin it by adding the frozen stuff!). Β 

  53. 4 stars
    The pie , out of the over looked fantastic! I can’t wait to chill , garnish and fast it. Will post again when it’s ready to eat. Thank you for this simple pie recipe.

  54. I made this recipe a few weeks ago using limes from my grandpa’s farm and it was lovely! Is there anywhere I can upload the photo?

  55. 5 stars
    Just made this and it tastes amazing. But mine is a bit runny. Not as firm filling as in your photos. what can I do next time to make sure it’s firm?

  56. I like its simplicity…I used regular crust and made a merangine…I had to improvise too hot to make a store run so I used what I have. It was a great way to use the whites..hate to waste food..its baking now.proof is in the pudding or should I say pie..lol

  57. Hi there,

    Quick question. When you mention 1 1/4 cup of crumbs and 1/2 cup of lime juice, what’s the measurement like for β€œcup” in measurement like ml ? Is there an international measurement for β€œcup”?

    Sorry first time trying this receipt.Β 

  58. 5 stars
    Thank you for this easy recipe, it was a big hit when my husband and I had dinner with my in-laws!!! Everyone loved it! πŸ™‚

  59. I’m a bit confused: does this use Key limes, or the largest Mexican limes more available at the market?

    1. Key limes are harder to find so you can use regular limes. You just need 1/2 cup juice. You can even use store bought key lime juice.

  60. 4 stars
    It’s very good — but I prefer to leave out the eggs and use 8 ounces of softened cream cheese instead. If you’re using bottled lime juice and have no limes of any kind, some grated lemon rind will still give you some added citrus sharpness. And, if you’re making the crust instead of using a store-bought one, try it with gingersnap crumbs. Ginger and lime go together beautifully!

  61. 5 stars
    Great and easy recipe. I have celiacs and subbed GF graham crackers. Nobody could believe it was gluten free. Thanks so much for sharing!

  62. Easy and delicious recipe. The only thing I would change is to make more filling. It didn’t fill the pie shell very much. I used regular limes and they tasted great!
