Ricotta Cheese Info

Fall in Love with Ricotta

I fell in love with Ricotta after attending a workshop with Giuseppe Licitra, President of the Consorzio Ricerca Filira Lattiero-Casearia (CoRFiLaC) in Ragusa, Sicily. During this workshop we watched as they broke the curd for Ragusano cheese with a big stick (and none to kindly at that).

As it turns out their intent is to drive out as much as 30% of the butterfat into the whey to be made into the richest tasting Ricotta I have ever tasted. The background behind this is that the final cheese (Ragusano) would not produce income for many months or years.

The Ricotta that could be produced could be immediately sold thus producing an income for the farms within a few days.

What is Ricotta Cheese

Ricotta has been a traditional cheese of Italy for many centuries. It was originally a means to strip proteins from the whey following the primary cheese making process. Proteins that would have otherwise been lost in the whey.

This was especially true in some of the longer aged 'Pasta Filata' styles (stretched cheese) such as Caciocavallo or Provolone and even in Parma style cheese where

Ricotta is a heat and acid precipitated cheese that can be made from whole or skim milk. When made from a mixture of milk and whey it is called Ricotone. Raw milk can be used for the production of ricotta cheese since the heat treatment during curd formation more than meets the heat requirements for pasteurization.

In the first step of the process either a live culture or an acid is added to the milk to lower the pH to 5.9-6.0. The mixture is then heated to 176-185F, for 15-30 minutes.

This heat treatment, combined with the effect of the acid causes the precipitation of the curd. Exposure to such a high heat results in denaturation of some of the whey proteins that would normally be lost with the whey. The resulting curd is composed of both casein and whey proteins, unlike a conventional curd which is almost all casein. The ricotta curd also differ from a conventional rennet/acid curd in that the ricotta curd is loosely bound and entraps air. This results in a curd that will float on the top of the cheese vat. Proper control of the pH and the level of agitation are necessary to ensure that the curd floats and does not sink. The collected curds are allowed to drain for 4-6 hours in a cool room and then ready for consumption.

Ricotone and Ricotta cheese are very high in moisture and contain most of the lactose from the milk. Therefore, the keeping quality is not very good. It may last 10 days at best.

Variations in Style

  • from whole milk
  • from whey (with or without added milk) .. this is usually called Ricottone
  • a drier version is made by extending the draining in the forms (One of the richest and most luxuriant versions comes from the Ragusano area of Sicily)
  • a very dry version (Ricotta Salata) made from extended draining and pressing under weight and followed by aging of several months or longer .. This can then become a table or grating cheese
  • Ricotta tastes and smells like the milk it is made from, so use the best and freshest dairy you can find. You can control the consistency of your cheese by the length of time you drain it
  • Richness can be increased by incorporating more cream in the Whole milk or Whey from your cheese making ... to the point that it will be almost like Mascarpone
