Years ago, in the 1970's, I had the good fortune to spend some time with , now Sir, Dai Rees, then a manager at Unilever Research, and his group in the Colworth lab outside of Bedford, UK. One of their foci was ice cream. In a conversation that I suspect he did not intend to be memorialized, Dai made the following comment. 'Processed foods have two main components. The firt is air, the second is water. Everything else is packaging!'

Great graphic!

I look forward to an addendum with frozen custard / french style ice cream (cream + egg + sugar).

yeah how could they forget the original: custard

Since it's not included in the graphic, here's some more info on frozen custard: it contains around 10% milk fat, and has an overrun of 15-30%.

I find it so interesting that air bubbles are a great factor in ice cream making. I learned the difference between each frozen dessert scientifically and what makes each frozen dessert special. I also learned about bonding between hydrogen, carbon, and oxygen which are really important in the composition of ice cream.
