It is commonly believed that winter during that age was a period of starvation, with very limited means of procuring food.
If the above is true, what did the commoners (peasants, serfs, etc) had to eat during spring? I think the crops would take months to harvest, there would still have some ice thawing.
Would they hunt? Was there a crop / fruit / vegetable that grew during winter and could be consumed in spring?
How much food was available? Was the "winter famine" over right after winter, or how much time did it take for food supply / distribution to spread out?
