Back in the day, I didn’t like “sour” desserts. Lemon bars, lemon curd, key lime pie – I didn’t consider those desserts. In my opinion, desserts are supposed to be sweet. But in the last few years, I’ve come around. I even chose a lemon cake with lemon curd filling for 1 tier of our wedding cake, and it was fantastic! (The second tier was my husband’s delicious choice of dark chocolate with salted caramel filling, and a coconut buttercream icing. The cake was made by our lovely friend, Danielle, who is a professional chef for America’s Test Kitchen (!) and an all-around amazing, kick-ass woman.)

Since I’ve come around, I have a whole set of new desserts to try. I’ve already made homemade lemon curd (which tastes great on top of ice cream or pound cake), so now I’m trying this simple key lime pie. This pie makes me think of summer and warm weather. It’s finally getting warm here in Boston (yay!), so this is a great way to bring the warm sunshine inside to your plate. The key lime flavor, plus some sour cream, has a hint of tang to it, which tempers the sweetness of the sweetened condensed milk.

What do you think of “sour” desserts? Are they your jam, or do you stick to sweet sweets?
