There is nothing like a little lasagna made with mascarpone cheese added to the white sauce, the minute it comes off the fire to turn it from, yea, that’s good, to Lord have mercy on my soul, that is one good white sauce. When you make it, don’t forget to cook the flour and the butter over a low heat, whisking constantly, until the roux loses that raw flour taste. Sear off a few bones for your meat sauce to add to it while it simmers, and then layer the whole thing together–meat sauce, white sauce, Parmesan and noodles–with the best Parmesan you can find, and either fresh, or something like a Barilla noodle, that doesn’t have to be cooked before you put it in the lasagna.
