The general information on candy Ruth Freeman Swain provides in How Sweet It IS (and Was): The History of Candy (2003) is nicely interesting, is both enlightening and extensive but is also not that intensive. In other words, Freeman Swain's text for How Sweet It IS (and Was): The History of Candy does not really delve deeply and therefore presents a basic and not all that thorough introduction to candy and its history. However, this absence of narrative rigour does not really matter all that much, is not really problematic since How Sweet It IS (and Was): The History of Candy is a picture book meant for young readers and/or listeners from about the age of six to nine or so and is therefore also not meant to be comprehensive and all-encompassing. And while for adult me, what Ruth Freeman Swain features in How Sweet It IS (and Was): The History of Candy makes me majorly (and punnily) hungry for more, for my inner child the textual thematics and contents of How Sweet It IS (and Was): The History of Candy are more than sufficient (and not to mention that if young readers do want or require more, there is also a very good introductory bibliography included in How Sweet It IS (and Was): The History of Candy).
But while textually, while educationally speaking, what Freeman Swain provides in How Sweet It IS (and Was): The History of Candy works really nicely and equally provides more than decent enlightenment to and for the intended audience mentioned above, except that in the section of How Sweet It IS (and Was): The History of Candy on maple syrup, it is both inaccurate and kind of disrespectful that only the USA and Native Americans are mentioned since maple syrup is of course also produced in Canada, that Native Canadians have similar if not the same maple syrup culture and lore as Native Americans do the and that in fact Canada is actually more famous for its maple syrup than the United States is, sorry, but we (and that is both my inner child and adult I) jointly really do not enjoy John O'Brien's accompanying artwork for How Sweet It IS (and Was): The History of Candy all that much. For one, O'Brien's colour schemes are a bit too washed out and not sufficiently brightly hued for us and that we also think that alongside of the illustrations, there should also be some photographs of candy etc. for How Sweet It IS (and Was): The History of Candy. And for two, while I, while we do understand that John O'Brien's pictures are obviously supposed to be humorous and perhaps even slightly parodistic, especially O'Brien's artwork depicting Native Americans, it is politically incorrect, it is visually disrespectful and aesthetically makes us both hugely cringe.
So yes, especially due to my inner child and my adult reading self's active dislike of John O'Brien's illustrations for How Sweet It IS (and Was): The History of Candy, we simply cannot and will not consider a rating of more than three stars, and that while How Sweet It IS (and Was): The History of Candy is still to be recommended for the information on the history of candy Ruth Freeman Swain provides, well, I would definitely point out the issues I have encountered regarding maple syrup.
