The word "perfect" is a one-size-fits-all label in the blogosphere, applied to everything from our lipstick du jour or the latest chocolate cookie to blow our minds. So when I use the word perfect to describe the dessert that I think has it all, the dessert that everyone should have memorized and ready to go, I do so with some trepidation. Does perfect go too far? No, it doesn't. Panna cotta can always be the right dessert — whether you're throwing a fancy party or a small one, have lots of time or no time, are gluten-free, dairy-free, allergy-prone, vegan, or simply craving a delicious and creamy sweet. It's perfect. Let me tell you why.
