Recommendations for making ice cream with milk and corn starch (corn flour)
Jeni's Splendid Ice Creams at Home by Jeni Britton Bauer has a (somewhat) similar base to this, in that it has no eggs, and uses a mix of milk and cream - along with a tiny bit of cream cheese to provide the requisite proteins, and corn starch to thicken.

In my opinion, it's one of the best ice cream bases out there.

I also have the Perfect Scoop, and have had no trouble switching the recipes I've tried from it over to Jeni's base.
