Query: Don't Waste Your Time!

This is the worst book of ice cream maker recipes I have come across. it Includes recipes that are not complete such as the "Enlightened Vanilla Ice Cream" recipe that calls for only cream, sugar and vanilla extract. I believe they left out a major ingriedient....maybe some egg whites or yolks to give it thickness. I tried this recipe and ended up with 100% liquid. What a waste of time!
