Another woman told of growing up in Finland and of a particular cold winter day when a cow was slaughtered for meat. The mother in the kitchen stirred a vat of sliced onions in butter, and the girls one at a time rushed into the field with deep metal pans to catch blood gushing from the cow’s slit throat. The blood was poured over the onions, and then that mixture was transferred into their largest mixing bowl, along with flour and salt and homegrown yeast. Now the girls took turns kneading, palpating the ingredients with their chapped hands as if restarting a stopped heart, their shoulders bent with the effort, their mother reminding them that this blood bread would be all they’d have to sustain them in the cold days ahead, while the meat cured. “Beat the old lady out,” the mother called to her daughters. Beat out the cranky lumps until the dough in your hands is elastic, forgiving. Leave nothing behind, not a speck of flour nor smear of blood in the shiny bottom of the bowl.
