Grant Barrett and Martha Barnette, hosts of the radio show “A Way With Words,” join us to explore the language of food. They discuss why some restaurant servers ask “Will you be wanting anything else?”—instead of simply “Do you want anything else?” And they explain phrases that seemingly don’t make a lot of sense, such as “in a pickle.” Plus, master spice blender Lior Lev Sercarz teaches us how to transform a meal using spices; we learn the step-by-step rules to perfect curry; and Adam Gopnik ponders climate change and the future of wine.
