Wow! You guys are great. As far as I can see..there aren't many recipes that include
flour, but there are several that include cornstarch.
I had a chance to interview Alice Medrich recently and she said the cornstarch helps add body and mouth feel to ice creams without adding all the fat (heavy cream, egg yolks, etc.)
Last night I was playing mad scientist and made the attached recipe. Notice it's just like Alice mentioned...very little fat, no eggs, and a good amount of cornstarch. Frankly, when I took it off the heat, it looked like pudding. I thought I totally ruined it but decided to proceed anyway. After churning and freezing, I have to say, for texture, this is one of the best ice creams I've ever made! Especially for chocolate, which I haven't quite nailed until now. (Re: the attached recipe--maybe my cinnamon was super fresh, but the flavors didn't meld very well for me...Next time I'll skip the cinnamon.)
I also recently made the Pumpkin Gelato from Saveur. I happened to make it shortly before my interview with Alice, so while we were on the subject, I mentioned how lovely the texture was on that too. She said it was probably due to the fiber. Fiber can have the same effect as starch...creating a super creamy texture without the need for added fat. I had the same outcome with the David Lebovitz Avocado Ice Cream. Wonderful smooth texture. She noted the fiber in that one too.
When I heard about the flour in ice cream, I popped Alice an e-mail. She drew an interesting parallel about it being a thickner...just like how some people use starch or flour to thicken fruit cobblers and pies. The thing is, both starch and flour, and tapioca flour, for that matter all react a little differently and that has an effect on "taste and texture and clarity." She noted it would be interesting to do a side by side comparison using the different thickeners.
With a little more research, I found recipes for the East Indian Kulfi ice cream that not only does it omit the eggs, but it also reduces the milk (no wonder it has such an intense depth of flavor!). One secret ingredient was a slice of white bread, trimmed, then soaked in milk to make a paste. Then add to the base. Interesting...
I told you all I'm geeking out on ice cream lately, right??? smileys/smile.gif
