I love potato hamburger buns. How could I turn this recipe into that? Should I use something similar to the ratio in the Parker House rolls recipe (part AP flour, part mashed potato flakes)? I've already told my husband that once we start grilling, these bad boys are making an appearance at our table!! How about just using the dough from a potato roll recipe, like the Parker House rolls, and shaping it into hamburger buns? Barring that, you could definitely substitute potato boiling water (water in which you've boiled potatoes) for the water in the recipe. Or, stir in 3 tablespoons potato flour. If you want to add mashed potatoes, you'd need to guess at the amount - should work, but I'm not sure how much you'd need to reduce the liquid by... PJH
