What do peasants in medieval time do in winter?

Winter time, from November through to February was surprisingly bounteous in terms of food for medieval people. In England vegetables such as beet leaves, cabbage, kale, celery, leeks, parsnips, spinach, swedes, turnips and cress were available (although the range became smaller as winter progressed). Stored Apples and Pears continued to be eaten, as were various nuts gathered from the wild.

These vegetables had been grown since Anglo-Saxon times and continued right through the medieval period.

It was really in early spring when the available foodstuffs became seriously depleted, since last year's crops had all but finished and the new season's crop was not yet grown to maturity. Early spring could be a time of hardship and shortages at a peasant's table.
