Manteca* begins where ricotta leaves off. Once the whey has been taken for that cheese, it is not discarded: acid whey is added as the ricotta forms, then the liquid is brought up to eighty-five or ninety degrees. Heat and acidity do the quiet work of gathering what still remains in the vat, turning a by-product into the start of something richer.
What rises is collected and left to settle. There is no hurry in that pause. Gravity thickens the mass, and the dairy waits until the next morning before anyone touches it again. The wait is part of the craft: a night of stillness after the heat.
At dawn the curd is crumbled by hand into a wooden bucket or one of tinned metal. From there it goes into a cotton cloth and is left to drain through a full day and night. Fingers break it small; cloth and time pull the last whey away. What remains is Manteca* as Regione Campania records it: not a flourish, but a sequence of heat, rest, crumbling and a long, slow drip.
