Tucking her hair up into the net, Cilla began to read the kitchen manager's list for the night's production. Item two made her pause in disbelief. Ninety-six-dozen blueberry muffins? That quantity was unprecedented in Cilla's tenure as night baker. It had to be a special order. She exhaled loudly, pursing her lips, and calculated in her head. She would have to quadruple the usual batch in order to get that yield. She looked away from the list and searched the kitchen visually for the batch book. She had never had to resort to it, but she knew it had to be in the kitchen somewhere. She was too well-trained to think she could simply increase the amount of every ingredient by a factor of four and expect the muffins to come out edible, much less attractive enough to sell. There was a formula and she knew she had to find it unless she wanted to suffer through making four separate batches.

Her gaze had just landed on the cupboard on the wall between the convection oven and the proof box when Marcy entered, tying her apron.

"Hey, Cilla. How's it going?"

"I was okay, then I read the production list. There's a special order for blueberry muffins--the usual production has to be quadrupled!"

"Eek," Marcy stated more mildly than the situation required. She was so laid-back, Cilla sometimes found her irritating.

"Do you know where the batch book is?"

Marcy began to survey the kitchen in search of it. After a moment, she stepped into the small hallway that connected the kitchen, storeroom and the office. In one corner was a steel cupboard. She tried its door. She had to struggle with it briefly, but it opened and revealed a stack of loose-leaf notebooks.

Marcy craned her neck and looked at Cilla, still in the kitchen.

"You'd better come here and look. I don't know what it looks like."

Cilla entered the hallway and looked at the contents of the cupboard. Her face suddenly lit with joy. "There it is!" she cried, reaching to pull one of the notebooks from the stack. "You must be psychic! Thank you!" she told her assistant. Marcy shrugged.

"Glad I could help."
