Sure, we all love mashed potatoes. But if you want a different dish, try these boulangerie potatoes. In France, when this potato dish was invented, the bakery (boulangerie) had one big oven for the town. That’s where people went to bake their potatoes, after all the bread was made. Meats were roasted on the top rack, potatoes below. This is why we use chicken stock, to recreate that roasted taste.
