Rumpuć — Poland

Rumpuć is a hearty potato dish reported from Poland, in which boiled potatoes are mashed together with cooked dried peas or beans into a coarse, filling purée, then topped with fried bacon and onion. It sits among the peasant dishes built around potatoes and legumes that are common across central and northern Europe. The dish is associated with Kashubia, in the northern part of Poland, a region shaped by sandy soils better suited to potatoes, rye and legumes than to wheat. Within Poland it belongs to a broader family of rustic mashes and one-pot dishes that combine a starchy base with a small amount of pork fat for flavor, made to stretch modest ingredients into a filling meal. To prepare it, dried peas are soaked and then boiled until soft while the potatoes are peeled and boiled separately until tender; the two are then mashed together, sometimes with a little of their cooking water, into a thick, coarse purée. Bacon and onion are diced and fried until golden, and most of this mixture is folded into the mash while a spoonful is kept aside to finish the plate. What distinguishes this version from a plain potato mash is the addition of peas or beans, which give the dish more body and a slightly grainy texture, and the fried bacon and onion stirred through rather than served as a separate garnish. The proportion of peas to potatoes, and whether butter or lard is used alongside the bacon fat, differ from one household to another, but the combination of mashed starch, legumes and fried pork remains the recognizable core of the dish.
