Mastering the Art of French Cooking — Julia Child

Published in 1961, this book single-handedly democratized French cuisine for English-speaking home cooks. Julia Child wrote it as a teaching manual, not a recipe collection — every instruction assumes you've never done it before and walks you through the technique step by meticulous step. The boeuf bourguignon recipe alone runs four pages. It's exhaustive, exacting, and rewarding in a way that no shortcut-driven modern cookbook can match. Still the gold standard 65 years later.
