I remember a movie from about 10-15 years ago, I only remember a part of it. There were a man and woman living in the Netherlands (I think) and she came into possession of a painting the she didn’t want to part with. Times were tough,  (there may have been a flood or something?) and they were eating a lot of potatoes. She didn’t want to sell the painting even though they needed to, and she had dipped into the seed potatoes that were the next years planting. I think the movie followed the story of the people who came into the possession of the painting.
