When my husband was little, he and his brother went to spend the night at their aunt’s house. The next morning, she made pancakes for them. Scott thought that the pancakes were studded with chocolate chips, so took a giant stack. Turns out they were filled with blueberries.
Because he wasn’t mentally prepared for blueberries, he spit out the first bite in surprise and yelled “yuck.” His aunt was mightily offended and despite his protestations, made him eat the rest of the stack. He has not touched a cooked blueberry since.
What this means practically is that when I’m cooking and baking for the two of us, I take care to avoid making things that involve blueberries (it’s the nice thing to do). I dearly love a blueberry baked good, however, and so at least a couple times a summer, when blueberries are in season, I make up some treat that my friends and neighbors might like so that I can have all the enjoyment of it without eating the whole thing on my own.
