The puffing gun is up and running! This week on Cooking Issues, Dave Arnold and Nastassia Lopez recap the first test of the Museum of Food and Drink's new cereal puffer! Later, Dave takes on some questions regarding bubble size in alcoholic drinks and flavoring Doritos. How can you get brown rice to stick together? Dave helps a caller preserve some cocktail cherries, and talks about his recent foraging adventures at Riverside Park. How would Dave make banana chips at home? Finally, hear about 'cat crap coffee' and 3D printing food! Thanks to our sponsor, ChefSteps.

"The bubble size of any given drink is due to the amount of CO2 you push into it and the temperature at which you serve it." [5:20]
