I've tried the grapefruit pie brought to our attention a few days ago by piccola, Dining Diva, and some others. I made *just* the filling, to see if it would be worthy of a crust & topping. Basically a curd, like lemon curd, but the most extraordinary shade of pink--just gorgeous! (I used ruby red grapefruit, lots of color) It contains both juice and zest, and has that unmistakable zing you experience when chewing citrus rind! If in a good flaky crust, and topped with plump sections of ruby grapefruit & whipped cream, I think this would be considered above average, somethin' special. Be sure your grapefruit is very good. Just thought I'd let the interested parties know this pie is worth pursuing.
