Living in Granada during college, I decided to cook fish tacos for my host family. Of course there's no such thing as fish tacos in Spain, so this was a unique delicacy for them. While stirring a lime/yogurt sauce, I was confused why it was turning bright red. Yep, I'd cut my finger slicing the lime. Had to throw it away and start from scratch. But once everything was done, they were pretty damn good, and the family still makes them from time to time to this day.
