Lesson 4 — Onion: The Foundation of Flavour

Onion Guide 
The ingredient that deepens flavour.

Onion is one of the quiet foundations of great cooking. 
It rarely stands alone, yet it shapes the flavour of countless dishes. When cooked properly, onion develops sweetness, depth, and richness that strengthen soups, stews, sauces, and marinades.

Inside this Spice School™ guide, you’ll learn how onion behaves in the kitchen and why chefs rely on it to build the base of flavour in so many recipes.

Inside this guide you’ll learn

• how onion builds the foundation of flavour

• why powdered onion behaves differently than fresh

• how chefs layer onion into a dish

• when onion should blend quietly into the background
