This document discusses cake formula balancing and common cake faults. It explains that a cake formula must balance tougheners, softeners, moisteners and driers. Tougheners like flour and egg provide structure, while softeners like sugar and fat soften texture. Moisteners provide moisture while driers absorb excess moisture. The key is balancing these ingredients. Common faults include cakes that rise and fall or sink from an unbalanced formula with too much liquid or sugar. Cakes can also have peaks from too strong a flour or fruits that sink from a weak flour. A crumbly cake results from over-creaming, too much shortening or sugar, or a weak flour-egg structure.
