Many key things occur during the preparation or consumption of food.
In a wealthy household, there might be an entire staff working in the kitchen. Scullery maids did the dirty work of cleaning endless amounts of pots and pans. Cooks slaved over wood-burning stoves and ovens, chopped fruits, vegetables and meats, rolled pastries all while issuing commands to those under their watch.
Imagine the conversations that took place. Most likely there was a fair bit of gossip tossed about the family and townspeople alike.
In the dining room circumstances were quite different. Wealthy patrons were waited on by unformed servants. Course after course was served. Conversation might have covered contemporary issues, politics, entertainments and relationships.
Things are very different in the homes of the less wealthy, even today. Instead of maids, the wife does the cooking and cleaning. Kids help out, and in more egalitarian marriages, so do the husbands.
Regardless, topics of conversation might be quite similar.
Your task is to write a story in which the preparation and consumption of food plays an important role. Establish the setting and key characters, then get the action moving. Dialogue is going to be important, so make sure there is enough to allow readers to see what is going on.
Have fun with this one.
