Frozen Key Lime Pie

.

I stepped out the back door this morning to let the dog out, and the air felt cool, light, and oh-so-slightly fall-like. I could breathe. Oh my goodness, I think my lethargy this past summer might have something to do with lower oxygen levels in my blood -- for the humidity all summer long I felt like I could hardly breathe.

Anyway, when I got that breath of fresh, cool air this morning, I realized there were some yummy summer recipes that I had not yet shared with you, one of which being this wonderful Frozen Key Lime Pie. I, myself, am not big on Key Lime Pie, but I tell you, I could have eaten this entire pie by myself, it was that good. The recipes comes from my new, favorite ice cream cookbook, A Passion for Ice Cream.

One thing I like about this cookbook is it not only offers great ice cream recipes, but it offers recipes using those great ice creams. This recipe, however, does not use ice cream -- it's made to be just this pie. The crust is made with sugar cone crumbs (yum!), and it is topped with a macadamia nut whipped cream, which we unfortunately had to do without because of my son's tree nut/peanut allergy (I'm sure it's wonderful, however and I have included the measure of nuts in the ingredients in case you want to use them). If you don't use the nut cream you could top the pie with some grated lime peel, or just leave is clean like I did.

Note: I used Rose's lime juice instead of key lime juice as neither key limes nor their juice are available at any of my local grocers.

Frozen Key Lime Pie

serves 8-10

printer version

12 sugar cones, broken up

6 T. butter, melted

6 large egg yolks

2 large eggs

1 1/4 cup sugar

1 cup Key Lime juice (I substituted Rose's lime juice available either in the juice aisle or with bar mixers)

1/8 t. salt

1 cup heavy whipping cream

Whipped topping

3/4 c. whipping cream

1 T. sugar

1/4 t. vanilla

2/3 cup macadamia nuts, toasted and roughly chopped (optional)

Place sugar cones in processor and grind them to fine crumbs. Add butter and pulse until combined. Press the crumbs in the bottom and up the sides of a 9-inch pie pan. Place in the freezer.

In a medium saucepan, whisk together egg yolks, eggs and sugar. Whisk in lime juice and salt. Cook over medium-low heat, stirring constantly with a heat-resistant spatula or wooden spoon, until thick, about 8 minutes. (The curd is done when you can briefly see the bottom of the pan as you stir.) Pour curd into a bowl set inside an ice bath and cool. 

When curd is cool, whip the 1 cup whipping cream until soft peaks form. Fold cream into curd. Pour into shell and freeze for at least four hours or until firm.

To serve: whip cream with sugar and vanilla until soft peaks form. Fold in nuts if using. Spread over pie and serve.

To make ahead: cover pie tightly and freeze for up to 2 days. Whipped cream can be made up to three hours ahead and placed on pie at serving time. (I found that the cream tasted just as good on the leftover pie after it had frozen, so this is your choice -- frozen cream or soft cream).
