Variations: Lemon Cream Filling; Lime Cream Filling; Vanilla Bean Cream Filling; Whipped Cream Filling

I developed this recipe as a filling to go with my Lemon-Orange Scented Chiffon Cake Recipe. I also love any citrus flavor, and this easy to make filling can be made in lemon or lime by simply exchanging the peels of the fruit or made in plain vanilla, folded into whipped cream.
