An artisinal cocktail book by two best friends and the entrepreneurs who invented the The Mason Shaker cocktail shaker and whose mission is to bring cocktail crafting out of the bar and into the home.

Design, cocktail, and culinary enthusiasts Eric Prum and Josh Williams realized that while cocktail bars have sprouted up just about everywhere, good drinks still couldn't be found in the one place where they always mixed them: at home with friends.

So, from their Brooklyn workshop, where they designed, created, and launched The Mason Shaker, a now-iconic invention that transformed a Mason jar into a cocktail shaker, they also created Shake. One part instructional recipe book and one part photo journey through their year of cocktail crafting, the book is a simple and inspirational expression of their seasonal, straightforward approach to drinks and entertaining: Mixing cocktails should be simple, social, and above all, fun.

Each recipe is presented visually, in four color photos, as well as in written recipes, making Shake both an arresting gift and a practical guidebook to simple, elegant cocktails.

ERIC PRUM and JOSH WILLIAMS have been best friends since they were freshman roommates at UVA. A decade later, they are founding partners in W&P Design, a product innovation company launched in 2012 with a Kickstarter campaign to manufacture a Mason jar cocktail shaker.

They are guest cocktail contributors for marthastewart.com and have been featured in the New York Times, Martha Stewart, Southern Living, Food & Wine, and on CNN among other media outlets.
