1 cup bread flour
1/4 cup instant mashed potatoes
2 1/4 teaspoons yeast (one package)
2 tablespoons honey crystals (or sugar)
2 tablespoons olive oil
1 teaspoon salt
1 1/2 cups cool water
Put everything except the water into the food processor and let it spin. Pour the water in through the feed tube as fast as the dough can take it in, and continue processing until it forms a ball.
Check the dough for consistency. Depending on the type of instant mashed potatoes used, the dough could feel gritty. When I buy them, I look for a brand with the fewest additives, and I found one that's basically just cooked, dried potatoes with no extra stuff. Which is great. The downside is that the pieces are like nuggets, so it takes a while for them to hydrate in the dough. If you're using flakes, they'll hydrate faster and you won't have that intial grittiness.
I miscalculated the speed of the rise a bit, and got the bread into the oven a little quicker than I should have. I didn't get as much oven spring as I expected, so the bread was a little denser than I wanted, but it's still a nice, flavorful loaf. If I was going to change something, I think I'd pop it into the fridge after taking it out of the food processor to take the chill off for a longer, slower rise.
