Mastering Spice: Recipes and Techniques to Transform Your Everyday Cooking by Lior Lev Sercarz with Genevieve Ko is a cookbook devoted to understanding how spices and spice blends can transform familiar everyday dishes. Sercarz, chef and owner of New York's renowned spice atelier La Boîte, presents more than 250 recipes that teach readers how to use seasoning creatively rather than simply following fixed recipes.

A distinctive feature of the book is its master-recipe and variation approach. Each section begins with a fundamental recipe and cooking technique, after which Sercarz demonstrates how changing the spices, blends, or supporting ingredients can produce substantially different flavours. This approach helps readers develop an intuitive understanding of seasoning, flavour pairing, spice combinations, and culinary technique.

The recipes span a broad range of everyday and more sophisticated dishes, including chicken soup, meatballs, roast chicken, vegetables, fish, lamb, short ribs, breads, salads, sauces, and even desserts such as brownies. The book explores spices from many culinary traditions, including ingredients such as cumin, coriander, cardamom, sumac, Aleppo pepper, saffron, turmeric, anise, mustard seeds, and various chiles.

Published by Clarkson Potter/Ten Speed in 2019, the hardcover edition contains 272 pages and carries ISBN 9781984823694. The book was also named one of the best cookbooks of the year by The New York Times Book Review.
