Brown butter, is traditionally made by simply putting some butter in a saute pan and cooking it over medium heat until the milk solids separate out, settle to the bottom of the pan, and begin to turn brown. This happens to us all the time when we get distracted with a patty of butter in the frying pan waiting to make french toast, eggs or grilled cheese. Often this is called "beurre noisette," although Escoffier calls brown butter Beurre Noir. Beurre Noisette is hazelnut butter (to him).
Nomenclature aside, browned milk solids are a delicacy that is vastly under-appreciated. The flavor of pure brown butter solids is savory but brings up connotations in the mind of caramelized milk. It is at once a novel roasted note that is neither completely toasted nor caramelized, but somewhere in-between. Brown butter, poured over light fish or gnocchi accentuates delicate flavors without covering up. A marriage of bass and flutes. And it brings up memories of the already-mentioned grilled cheeses I used to eat all the time growing up (as long as the butter didn't get black!).
So a few weekends ago I set out to make brown butter ice cream. My issue was that many others alluded to it on the internet, and there was even one recipe, but I was not satisfied with anything I read so I'm offering my own. One of the primary differences between this recipe and others you might find is that I keep the fat content of the ice cream around a happy 12-14%, nothing like the 20%+ I calculated with one of the more popular online recipes. This is done by substituting heavy cream with skim milk and making up the difference with butter fat, rather than just adding butter fat. The other major difference is that I bump up the amount of solids in my butter in order to make a super concentrated syrup, which is then used in the ice cream, providing an extremely strong flavor. Not light and subtle at all. It will *definitely* hold up to any sauce or pairing you put with it.
Brown Butter Puree
Melt 1 pound butter in a sauce pan. Add 200g non fat dry milk powder and cook on medium heat. At first it will be thick and homogenous. Keep stirring and cooking, scraping the pan thoroughly as you go. Eventually it will start to brown and will separate out into a clear solid and butterfat portions. It WILL happen eventually - you can turn the heat up if you get concerned. You want the solids to turn a dark brown without turning black. The entire process will take 30 minutes or more, especially the first time.
Strain the butter in a fine mesh sieve. Save 6 fl. oz. of the liquid portion, and all of the solids. (Actually, save the rest of the liquid portion to use in your everyday cooking as clarified butter, but 6 oz. is what we need for the recipe).
Transfer all of the solids to a blender. Add just enough water (or skim milk if you prefer) to blend to a thick puree. Let this rip for 10+ minutes. It will be sandy at first, but eventually you will achieve a smooth puree. Reserve.
