From The Heart and Craft of Life Writing:
Although few things bond people like food and sharing recipes, I didn’t intend to include recipes in my mini-memoir, Adventures of a Chilehead, for several reasons:
1) Some of the stories are set in restaurants and I couldn’t include recipes for those.
2) Recipes for things like frijoles, chile con carne and enchiladas are easily found on the web.
3) When I cook, I use recipes as mere suggestions and cook by the seat of my pants based mostly on what’s in the kitchen at any given time. How do you write recipes for that?
4) Some ingredients, like chile powder, are unreliable in strength.
The finished book bears the subtitle “A Mini-Memoir with Recipes.” Obviously I changed my mind, primarily because most people who read early versions of the manuscript told me they wanted recipes.
. . . .
Most memoirs that include recipes put a single recipe at the end of each chapter. For example, Ruth Reichl’s Tender at the Bone and Judith Newton’s Tasting Home: follow this pattern. Since some of my stories take place in restaurants or feature hot pepper sauce, and some stories spin off three or four recipes, it didn’t make sense to put them with the chapters. Besides, the length of the recipes would interrupt the flow of the stories.
