If you are a pie baker, we hope you have found our All-Butter Pie Dough, which is one of our very favorite low FODMAP basic recipes. This recipe is similar to our pie dough, but with slightly different ingredients and a different preparation technique.   Tarts, formed in tart pans or within tart rings, eventually have to be sturdy enough to be freestanding. Same thing with a crostata – there is no pie pan supporting the dough. Because of these needs, our crostata and tart dough is a bit sturdier than our pie crust. This tart dough recipe has some extra xanthan gum to help it be as easy-to-work-with as it is. I do not consider it optional.   The crostata/tart crust is very easy to make and has a wonderful flavor. Make sure you have it prepped and ready to go.
