I addressed this in a new section at the front of the book, after it came up on Reddit and Tumblr: "A few recipes call for fancy kitchen equipment, but in my work with low-income families in New York, I have found that items like blenders, food processors, and electric mixers are not as rare as you might think. I did not, however, attempt to tackle the very real situation of people who have no kitchen, no equipment, and no space to prepare food. I simply cannot hope to do those issues justice in the bounds of this project."
More to the point, the kitchen equipment is a /convenience/, but whenever possible, I explain how to prepare the dish without that stuff. (If you find a page where I don’t (besides smoothies), please let me know, and I’ll fix it before the book goes to press!)
