Lesson 1Emulsifiers, binders, and texturants (lecithin, xanthan, gelatin, egg, psyllium): roles in structure and mouthfeelExamine emulsifiers, binders, and texturants such as lecithin, gums, gelatin, egg, and psyllium. Learn how they stabilise emulsions, improve crumb, and control spread, chew, and aeration in diverse pastry formats for everyday use.
Lecithin in doughs, batters, and fillingsXanthan and other gums for viscosity controlGelatin and alternatives for gelling systemsWhole egg, yolk, and white functional rolesPsyllium as binder in gluten-free formulasBalancing multiple texturants in one recipeLesson 2Healthy fats (olive oil, nut oils, high-oleic sunflower): plasticity, flavour, shelf stabilityExplore healthy fats such as olive, nut, and high-oleic oils. Understand plasticity, melting profile, flavour release, and oxidation, and how to replace butter while preserving flakiness, tenderness, and shelf stability in hot climates.
