Depending on the location schiacciata is also called ciaccia, schiaccia or stria. For many years the different denominations left me too confused to search for the recipe, but now I am happy to have found it by accident.
I first encountered the potato cheese bread decades ago, when we were driving around Monteveglio in the hills south of Bologna looking for a place to have lunch. It’s a hilly and sparsely populated area with few bars and restaurants. At least, we did not find any at the time, so at the end we entered a small grocer asking for anything lunch-like. The shop was out of bread, but they had some schiacciata di patata left over, which we could have with cheese and salumi. Though crisp on the outside, the bread was moist and juicy and it made an unforgettable picnic that can be easily reproduced with this simple recipe.
350 gr potato
350 ml tepid water
200 gr flour

Grate the peeled potato or slice it thinly on a mandoline and mix it with the batter.
