Migliaccio

An old sweet of the Campanian countryside whose name records a grain it no longer contains: «migliaccio» comes from the Late Latin «miliaccium», a bread or cake of «miglio», millet, which was the cheap grain of the poor before maize and refined wheat. Carnival, the feast before the Lenten fast, was the moment to use up what the farm had, and early peasant versions were enriched with whatever the stables and coops gave — milk, eggs, ricotta, a little sugar when there was any. Older accounts also tie the dish to the pig-killing of winter, when pig's blood was sometimes worked into a dark «migliaccio», a relative of the Neapolitan blood pudding sanguinaccio; this savoury-to-dark line is documented but the connection is not firmly dated. From roughly the late 18th century the recipe settled into its modern sweet form, with durum-wheat semolina replacing millet flour and the blood gone, leaving the semolina-and-ricotta Carnival cake known today.

Cut into a wedge and it is dense and moist, somewhere between a baked custard and a very fine polenta cake — smooth on the tongue but with the faint, pleasant grain of cooked semolina underneath. The dominant flavours are orange and lemon zest and vanilla, carried on the milky tang of ricotta, sweet but never cloying. It is eaten cold or at room temperature, when it firms up and slices cleanly; warm from the oven it is too soft to cut. A good migliaccio is silky and just set, the top barely coloured. A bad one is either rubbery and eggy from too long in the oven, or wet and collapsing in the middle from too little time, and a heavy hand with flour or leavening turns it into an ordinary sponge, which it is not meant to be.

The cake sets on two things: the gelatinisation of semolina starch and the coagulation of egg and ricotta protein. Cooking the semolina in milk first swells and bursts its starch granules into a thick, smooth paste, which is what gives the finished cake its body and its custard-like, sliceable texture without any flour scaffold. The beaten eggs then coagulate in the oven and bind the whole mass, while the ricotta contributes both fat and curd protein for a moist, tender crumb rather than a dry one. Because there is essentially no raising agent, the cake should be baked gently and not over-baked: too hot or too long and the egg proteins tighten and squeeze out water, turning it rubbery and weeping. The citrus zest carries fat-soluble aroma oils (limonene and the like) that bloom in the warm batter, and resting the cake fully cold before cutting lets the starch and proteins firm into clean slices.
