The Science Session

The kitchen as a laboratory — what actually happens when food meets heat, acid, fat, and salt.

Marian spent time in Heston Blumenthal's development kitchen, where the question was never what to cook but why it worked. This session applies that thinking to techniques you already use. The Maillard reaction, emulsification, osmosis, denaturation — the underlying science of cooking, explained through dishes you eat rather than diagrams you study.

This is not molecular gastronomy for its own sake. It is a clear understanding of why your steak goes dry, why your hollandaise breaks, and how to stop both from happening again.

What you'll learn

• The Maillard reaction in practice: why browning at the right temperature is categorically different from browning at the wrong one
• Emulsification: building and stabilising sauces that hold without breaking under heat or time
• Salt and time: why salting in advance changes texture and structure, not just flavour
• Temperature precision: what cooking sous vide reveals about protein and how that applies to every other method
• Acidity as a tool — how lemon, wine, and vinegar change the physical behaviour of ingredients
