Dave and Nastassia are back! This week on Cooking Issues they discuss the merits (or demerits) of having old-school arcade games in bars, "alternative" ketchups, xanthan gum, adding habanero peppers to butter cream frosting, the dress code at Roberta's, welding, seltzer, vacuum-sealing garlic, Fahrenheit versus Celsius measurements in cooking, and a Spinzall update!
