Can a 19th-century potato biscuit recipe outperform the modern dinner roll?
In short: In 1886, Mrs. Rorer published a recipe for Potato Biscuit No. 2 that utilizes a clever, early form of tangzhong-style gelatinization. By blending yeast fermentation with potato starch, this slow-rise technique produces a dinner roll with a remarkably light, fluffy texture that challenges our modern expectations of home baking.
The 1886 recipe from The Philadelphia Cookbook by Mrs. Rorer offers a fascinating glimpse into 19th-century baking science. Unlike modern quick-rise breads, this process relies on a multi-stage fermentation that begins by scalding flour with the water used to boil potatoes. This step creates a gelatinized base that, when combined with mashed potato, provides the foundation for the dough's unique structure and texture.
The process is intentionally slow, requiring patience from the home baker. After the initial potato-flour mixture is prepared and cooled to a lukewarm temperature, yeast is added and allowed to rise for approximately four hours at 72 degrees Fahrenheit. Once light, this mixture is incorporated into a second batter of scalded milk, butter, and flour, which undergoes a further two-hour rise. Only after this second stage is the final dough formed, kneaded for fifteen minutes, and shaped into individual biscuits.
While modern conveniences like stand mixers can assist with the kneading process, the core mechanics remain rooted in traditional techniques. Bakers of the era often sourced their yeast directly from local breweries, a stark contrast to the standardized products used today. By allowing the biscuits to rise in a greased pan without touching, the recipe ensures a uniform bake in a quick oven over twenty minutes. Whether these historical rolls truly surpass modern versions is a matter of personal taste, but the method remains a masterclass in using simple, starchy ingredients to achieve superior crumb quality.
