I noticed a couple of comments on the Sharpe Dynasty thread asking how to complete the Bad Apples opportunity and thought I'd share my idea.
Just to see what would happen, I sent one of my Sims on a catacombs trip or two. One of the things she found was an apple seed. When it grew to a tree, it was Horrifying quality and produced low-quality apples, many of them Bad or worse. I still have them in the fridge (I'm glad only prepared dishes spoil!) and will use ten of the worst if I get the opportunity in the future.
Best of luck!
