I made it basically as written except I did substitute Greek Yogurt for the Sour Cream as that is what I had on hand, and I tend to prefer yogurt to sour cream in most things that I make. It has a similar texture and worked very well. I used plain greek yogurt but I wonder if using a key lime flavored yogurt (like Oikos Key Lime Greek Yogurt) would be a nice way to get more key lime flavor in there, or if that would be too much in addition to the key lime juice? What do you think?

I also could not find Key Limes or juice where I live so I took your advice and used a 50:50 mix of lime juice and lemon juice which tasted great.

This was so easy to make and very tasty. A wonderful summer pie. I will definitely be making this again and am very glad that I found your website. I’ll certainly be checking out more of your recipes. Thank you very much!
