Deep Dish Key Lime Pie

Last week my son Preston turned 21.  It was hard for me to adjust last year to his no longer being a teenager, but I'd had a year to adjust to the idea of his being a full-fledged adult, so I was ready to celebrate with him!

Adult or not, he's still my boy.  And I still get the honor of making whatever kind of birthday cake his heart desires.  This year, it wasn't a cake he was craving; it was pie.  Key lime pie.

We don't live anywhere near the Florida keys, and good Key limes are hard to find around here.  So technically this is a Persian lime pie, but that doesn't sound nearly so good, does it?

I started looking for Key lime pie recipes, but I couldn't find one that quite delivered what I was wanting.  So I experimented and came up with my own.  If I really can't call it Key lime pie, I know what I'd call it instead: Sublime Lime Pie.  Because that's what it was.

The crust is a simple graham cracker crust.  I've used this recipe for many years, and I think it's just the right proportion of crumbs to sugar and butter.

You'll need 1 1/4 cups of graham cracker crumbs.  I make my own by crushing a sleeve of graham cracker sheets in my food processor.  You could crumble the crackers by hand by placing them in a ziptop bag and crushing them with a rolling pin or mallet.  One sleeve of graham crackers should yield a little more than you need.  You can also buy graham cracker crumbs.  But I would not recommend buying a pre-made graham cracker crust.

Melt 1/3 cup (5 1/3 Tablespoons) of butter (I do this in the microwave).  Add 1/4 cup sugar and the cracker crumbs.  Mix well.

Dump the crumb mixture into a deep-dish pie pan (this is the pie pan I have*); form into a crust with your fingers, and bake at 350 degrees for 10 minutes.  Set aside.

The filling is special mostly because there's a lot of it.  To fill a deep-dish pie crust, I made double the amount of filling I'd otherwise use.  (Note: I had a tiny bit of filling that wouldn't fit in my deep dish pan without running over.  If I'd known to expect some extra filling, I might have made a few tiny pies by making some extra crusts in muffin tins.)

The filling takes a few minutes to make, but it's quite simple.  First, you need some fresh lime zest.  This recipe requires a heaping tablespoon of zest, which was the zest of three of my limes.  I don't have a zester; I just use a microplane grater and it works just fine. (This is the grater I've had for years.*) A tip: zest lightly, getting just the top layer of skin from limes that you've washed and dried thoroughly.

Next, you need fresh lime juice.  Bonus: the zested limes are so easy to squeeze!  No bottled variety of juice by itself will suffice for this recipe, in my opinion.  Some fresh lime juice is required. I do think you can use half fresh juice and half bottled Key lime juice with good results. (This is the juice I like best.*)

As you can see, I like using the citrus juicer attachment for my KitchenAid mixer. (This attachment is the bomb, and it's not expensive—check it out!*)

Then you'll need just the yolks of four eggs.  Set the whites aside for another use; you won't need them for this pie.

And last is the magic ingredient: sweetened condensed milk.  TWO cans.  That's the real "key" to this Key Lime Pie.

After you've mixed the ingredients, you simply bake at 350 degrees for about 25 minutes, just long enough for the custard to set up.  Then you cool the pie completely before serving, and it dishes up beautifully.  It's extra-good with fresh whipped cream on top:

After Preston had blown out the candles on his birthday cake pie, imagine my delight when Jack said, "I think this may be the best pie you've ever made."  This recipe is a keeper!

Here it is:

Sublime Key Lime Pie
(Deep Dish Key Lime Pie)

1 1/4 cups graham cracker crumbs 
1/3 cup (5 1/3 Tablespoons) butter
1/4 cup sugar

Melt butter.  Mix cracker crumbs and sugar into melted butter.  Press crumb mixture into deep dish pie pan. Bake 12 minutes at 350 degrees.  Cool.

1 heaping Tablespoon lime zest
1 cup lime juice
4 egg yolks
2 cans sweetened condensed milk

Beat together lime juice, egg yolks, and lime zest.  Stir in sweetened condensed milk.  Mix until thoroughly combined.  Pour into prepared crust.  (Depending on the size of your pain, you may have a bit of filling mixture left over.)  Bake at 350 degrees for approximately 25 minutes or until set.  Remove to a wire rack to cool.  Chill well before serving.
