Crumbfolio is a small-batch baking notebook for home bakers who want to understand their ingredients, improve their technique, and make reliable recipes. Its practical approach centers on weighing ingredients, recording results, and learning how each baking step affects the finished loaf or bake. Recipes use baker’s percentages, making it easier to compare formulas and scale batches accurately.

The notebook offers short guides to baker’s percentages, pantry staples, measuring, and oven use. It explains the roles of flour, yeast, chemical leaveners, fats, sugar, and salt, with advice on weighing, temperature, proofing, and judging when bread is done. Crumbfolio also features small-batch recipes, including an everyday white loaf, buttermilk soda bread, and cookies, with ingredient weights and step-by-step methods. A working recipe-scale calculator helps adjust batches to different sizes, while quick-reference information covers spoon measures and temperatures. Metric weights are used throughout, and oven temperatures are provided for conventional and fan ovens. Designed as both a learning resource and a practical baking companion, Crumbfolio helps users turn recipes into repeatable methods.
