Mastering the Art of French Cooking: Selected Recipes reduces its price to $1.99, originally $4.99, in celebration of Julia Child’s 101st birthday. Happy Birthday! This low price is only available for an extremely limited time: ending this Sunday, August 18th.

The app features 32 recipes from “Mastering the Art of French Cooking”, color photographes of each finished dish, 30 clips from Julia Child’s “The Way to Cook” videos, and much more.

“’Mastering the Art of French Cooking’ remains one of the seminal cookbooks of all time,” said Tony Chirico, President of the Knopf Doubleday Publishing Group, in a press release. “Our goal was to make this standard work available to the growing generation of mobile and tablet readers. It’s hard to improve on a classic, but with the updates we’ve added, readers will feel as if Julia is with them in the kitchen. And who could be better company?”
