@dish_by_david: in three days, a brick of bread becomes a drink. one that an entire civilization lived on for a thousand years. nobody threw bread away. not in a slavic household. tsars drank this. peasants drank this. the same recipe, at every level of society. they never called it a drink. they called it food. #kvass #fermentation #slavicfood #guthealth #probiotics #fermenteddrinks #foodhistory #zerowaste #brinelab #dishbydavid
