Brian, I am not sure I can follow Yakutas' entire post.
The rich tasting ice milk that I make, which tastes like a rich french vanilla ice cream, is to use the custard method. I can not find my recipe at the moment, but you use eggs, sugar and milk and cook it. Then chill this custard mixture, I chill overnight. The next step is to add the vanilla and cream, except I use milk in place of the cream. Say the recipe says to add 5 cups of cream, I add 2 1/2 milk.
I follow the recipe that came with my electric ice cream maker. I use the recipe to make 6 quarts of ice cream, but my maker is only a four quart. So the custard is for a 6 quart maker, when you do the last step before freezing, there is only a small space to add the final fluid, milk in my case. I use a higher ratio of custard to milk/cream than the recipe calls for. I also add some peppermint oil and chocolate chips. It is a very decadant ice milk.
