9 Ratios Every Chef Needs to Know

The Power of Ratios in Professional Prep

For a professional chef, memorising specific recipes is far less valuable than mastering core culinary ratios. In this editorial breakdown of Fallow's masterclass, we explore how understanding the mathematical relationships between ingredients unlocks ultimate freedom in the kitchen. Transitioning your brigade from fixed-weight recipes to fluid ratios ensures seamless scaling, rapid troubleshooting, and effortless adaptation to seasonal ingredients. Whether you are prepping for a high-volume banquet or refining a daily à la carte menu, these foundational formulas provide the structural guardrails every chef needs. By committing these formulas to muscle memory, chefs can maintain consistency across different shifts and junior prep cooks, ensuring that every sauce, marinade, and emulsion meets the restaurant's standards without constant supervision.

Cold Emulsions, Acids, and Preservation

The guide begins in the garde-manger section, detailing the precise chemistry required to build stable cold emulsions like mayonnaise and vinaigrettes. A chef must understand the tipping point of egg yolks and oil; rushing the stream of fat or miscalculating the acid balance results in a split sauce. Beyond emulsions, the video explores the structural logic of preserving liquids. When mastering quick pickles and fermented hot sauces, the ratio of water, vinegar, salt, and sugar is crucial. Getting these proportions right ensures food safety and optimal crispness, preventing the mushy texture that ruins a chef’s prep. Rather than relying on guesswork, adhering to standard liquid-to-acid ratios allows for endless customisation with aromatics, chillies, and seasonal produce.

Hot Emulsions and Bound Proteins

Moving to the hot line, the focus shifts to starch-based thickeners and warm emulsions. The classic roux-to-liquid ratio forms the backbone of a silky béchamel and its decadent derivative, mornay. The pitfall here lies in temperature control and cooking out the flour to avoid a grainy finish. Similarly, the delicate balance of egg yolk, acid, and clarified butter in a hollandaise requires precise heat management to prevent scrambling. Finally, the guide covers the mechanics of bound proteins, specifically meatballs. A perfect meatball relies on the exact ratio of meat to panade or breadcrumbs and eggs, ensuring a tender, juicy texture that holds its shape during searing and braising without becoming tough or rubbery. This systematic approach to binding is what lifts basic comfort food into a refined, repeatable dish worthy of a professional menu.
