Enjoy homemade Key lime pie ice cream by flavoring a simple ice cream custard base with Key lime zest, Key lime juice, and graham cracker crumbs. 

How to Make It

Step 1

Whisk together first 3 ingredients in a large heavy saucepan. Gradually whisk in milk and half-and-half. Cook over medium heat, stirring constantly, 8 to 10 minutes or until mixture thickens slightly. Remove from heat.

Step 2

Whisk egg yolk until slightly thickened. Gradually whisk about 1 cup hot cream mixture into yolk. Add yolk mixture to remaining cream mixture, whisking constantly.

Step 3

Pour mixture through a fine wire-mesh strainer into a bowl, discarding solids. Cool 1 hour, stirring occasionally. Place plastic wrap directly on cream mixture; chill 8 to 24 hours.

Step 4

Pour mixture into freezer container of a 1 1/2-qt. electric ice-cream maker, and freeze according to manufacturer's instructions; stir in Key lime zest, Key lime juice, and crushed graham crackers halfway through freezing. Let stand at room temperature 5 to 10 minutes before serving.

Step 5

I do not have a ice cream maker. Can I use a loaf pan and stir it often?

I like the sweet, tart taste of Key Lime. This did have the tartness of limes, but I did not find it sweet at all. If I do give this one more try, I may add more sugar in the cooking process and perhaps try the whipping cream. I did appreciate the advice to add the graham cracker at the very end

I made with regular sugar, whole milk instead of 2% and Nilla Waffers instead of graham crackers. F-A-N-T-A-S-T-I-C

This was a hit with the folks at work! I couldn't find key limes so I just used limes and it still was great! 1 suggestion: Add in the graham crackers right before you finish mixing so they don't get pulverized or mushy... Will make again!

Excellent, my first review of any recipe. This is all 5 stars plus. I didn't change a thing.

Yum! This was delicious. A close comparison to one of my favorite local ice cream shops Key Lime Pie Ice Cream! I decided I wanted it really creamy and used heavy whipping cream instead of milk. It is really creamy and delicious! My husband who is not a big fan of key lime really enjoys this as well. Can't wait to make it again!!
