It occurred to me the other day that I had never told you why I don’t use mayo in my sandwiches. Indeed, if you look through my sandwich and panini recipes you’ll find none with mayo, and plenty with sour cream, cottage cheese or mustard. I know mayo is a very popular sandwich ingredient, and for good reason: you need a good creamy component to “bind” everything together and to turn the sandwich into a coherent whole. Still, we find mayo way too heavy and not particularly flavorful, and this is why I’ve been using other ingredients in its place. We’ve always been big fans of sour cream and cottage cheese (both of them lighter than mayo, in our opinion), so why not use these in panini or sandwiches? Moreover, on some occasions, I turn to other less used ingredients and I take advantage of their luscious creaminess to create a satisfying light lunch. Such is the case with the sandwich I am going to write about today, whose creamy component is a fried egg.
