Full disclosure: neither of us actually has an Aunt Melba. Rather, the combination of peaches, raspberries, caramel-y turbinado sugar, and vanilla are inspired by the classic peach Melba dessert. We sometimes name new recipes after fictitious relatives when entering them in contests to give them an air of authenticity. This fairly traditional lattice-topped pie was certainly a good candidate for such attribution. Does it help? Maybe or maybe not, but it certainly keeps us entertained!
