Yes I do post and follow three or four Russian cooking forums. It is not that simple, the products that are available there not alwasy available here. When they are available here they are not kosher, most of the time.
Red Mill sells kosher flour year round and King Arthur has it available prior and leading up to the holy days such as Passover. Although I imagine the shipping cost can break the bank. Also most major supermarkets will sell kosher items leading up to the holy days. My store tries to make all ethnic groups happy. They have a dedicated aisle that changes from one ethnic group to the next. It all depends on the next holiday. And it sells Red Mill year round.
