I'm copyediting a cookbook that contains a recipe for a Grand Marnier souffle. The directions for making the souffle base are:
"Bring milk and sugar to a boil. Stir constantly. Melt the butter in a separate pot, making sure the pot is large enough to hold the addition of the boiled milk. Do not let the milk over-boil in the pot. Add the flour to the melted butter. Add the boiled milk mixture and cook for one minute. Remove from heat. Allow to cool."
I'm not at all sure what the author means by "over-boil" and I don't understand why the milk has to be kept at a boil to make a good base. I should think that it would be OK to bring the milk and sugar to a boil and then turn the heat down, or even remove them from the heat, while one was making the roux. I've certainly had success making gravies, sauces, and souffles with liquids at all temperatures, from hot meat juices to cold milk from the refrigerator. However, I'm not a professional. Perhaps I don't know the difference between a souffle that is just OK and one that is superb. Does boiling milk do a better job of expanding the particles of flour? Is hot milk better than cold? Would very hot milk do just as well as boiling milk?
I should perhaps add that the author got this recipe from a pastry chef and doesn't seem to be a world-class cook herself. So she may have misunderstood some of his directions. But ... I can't go over the author's head and ask the chef.
