Gerald the Sourdough Starter
When Kai's dad married Dev's mom, Kai got a stepbrother and a jar of goo. The goo lived on the kitchen counter, and it was named Gerald. It was a sourdough starter, which is a mixture of flour and water that bubbles and smells a little tangy. Dev fed it every morning, the way a person would feed a pet.
Kai thought the whole thing was disgusting, so he held his nose when he walked past and called it "the swamp."
One Friday, Dev left to spend the weekend with his dad. "Please feed Gerald," he said. "One spoon of flour, one spoon of water, and a stir."
Kai nodded, but he forgot, and on Sunday he looked at the jar and saw that Gerald was flat, with gray liquid on top. Kai gulped. He measured the flour and the water, stirred them in, and whispered, "Sorry, Gerald."
By Monday morning, small bubbles were rising again.
When Dev came home, Kai told him everything. Dev looked in the jar and grinned. "Gerald is tough," he said. "He was just hungry." Then he asked, "Want to help me bake bread with him?"
Kai did. He ended up with flour on his nose. When the loaf came out with a crackly crust, he took a bite. "Not bad," he said, "for a swamp."
