Inmates are always asking to adapt their skills. One of the most fluid skills of the service industry an for life is cooking! We prefer to have a plethora of general cooking skills books and also books catering to specific interests (e.g. Cajun cooking, BBQ, Vegan, etc.). It's best if they are thin and paperback because big hardcovers end up costing a lot more postage. Get a cookbook from Grandma you don't need? I know someone who would love it!!
