Of course I use Key Lime juice! It wouldn't be key lime pie otherwise.I also put lime peel in the mixture. :-)
Well, I know a lot of Yankees use regular lime juice, dye it green, and cover it with meringue. That's what I thought key lime pie was when I lived in Michigan. After moving to Florida, I got spoiled on the real stuff. Now I'm in New Jersey, and I sure miss real key lime pie. Sounds like yours is pretty close. I'll be right there.
