the original recipe was called a “slump” although technically it was a cobbler; we turned it into a pandowdy. mostly because we liked the name, and because we rolled the dough. we’re going to call this recipe pandowdy from now on, even if it’s a cobbler with dropped dough, just because it’s so much fun to say.
the recipe works beautifully with 12 hours souring: just replace the 3/4 cup buttermilk with 1/2 cup sourdough starter and, depending on how moist you need to make it (i.e. rolling vs dropping the dough) either omit further moisture (rolling) or add up to 1/2 cup milk or mylk or water (dropping). we used lard (we raise pigs) but coconut oil works great for vegan option; butter for non-piggy option. [edit: to sour, cut fat into dry flour & oats, gently incorporate the sourdough. next day, add the leavening agents right before cooking / baking]
K can’t do rhubarb, so we used strawberries from our garden, plus blueberries.
we also omitted the applesauce (didn’t have any) and it worked out just fine. we baked ours so the topping would get crispy. it was very nummy.
