I've been brining pickles, which is a whole process. You're supposed to get stuff floating to the top of the bucket from the fermentation which is deliciously referred to as "scum." I was concerned because I was only getting a tiny amount of bubbles, not at all what I was seeing described, which made it sound like you had to ladle the scum off every couple of days.
You are also supposed to cover the bucket but let air in a little bit, so I had it covered with a towel.
Last night I came home and the towel had slipped, leaving a portion uncovered, and the bucket was FULL OF SCUM.
I was so happy I danced around for a few minutes, shouting, "Woohoo, scum! We have scum, people!"
And then it occurred to me that my life has gotten a little weird.
