Ricotta - Camera di Commercio di Macerata

Ricotta is a creamy white, mild, fresh cheese with a soft texture and a slightly sweet flavour. It is a whey cheese made from sheep (or cow, goat) milk whey, left over from the production of cheese. Like other whey cheeses, it is made by coagulating the proteins that remain after that the casein has been used to make cheese, notably albumin and globulin.

Ricotta (literally meaning "recooked") protein can be harvested if the whey is first allowed to become more acid by additional fermentation (letting it sit for 12–24 hours at room temperature). Then the acidified whey is heated to near boiling. The combination of low pH and high temperature denatures the protein and causes it to precipitate out, forming a fine curd. Once cooled, the curd is separated by passing through a fine cloth. Ricotta curds are creamy white in appearance, slightly sweet in taste, and contain around 13% fat. In this form, it is somewhat similar in texture to some cottage cheese variants, though considerably lighter. It is highly perishable. However, Ricotta also comes in aged varieties which are preservable for much longer.

 

 

 

Basic tortellini with ricotta and pine nuts


 

For the pasta

·        200g/7oz ‘00’ pasta flour, plus extra for dusting

·        2 free-range eggs, lightly beaten

·        12 large fresh basil leaves, plus 18-20 small basil leaves, plus extra to serve

·        225g/8oz buffalo-milk ricotta (or cows’ milk ricotta)

For the pesto

·        50g/1¾oz fresh basil leaves, chopped

·        10g/¼oz toasted pine nuts

·        25g/1oz parmesan, grated

·        garlic clove, crushed

·        25ml/1fl oz extra virgin olive oil

·        50ml/2fl oz olive oil

·        salt and freshly ground black pepper


 

 

Directions:

1.     Blend the flour and eggs together in a food processor until the mixture resembles breadcrumbs. Turn the mixture out onto a lightly floured work surface and squash the crumbs into a ball of dough. Knead the dough for 4-5 minutes, or until smooth and elastic. Wrap the dough in cling film and chill in the fridge for 20 minutes.

2.     For the pesto, grind the basil, pine nuts, parmesan and garlic to a rough paste in a pestle and mortar. Gradually pour in both the oils, stirring as you add them. Season, to taste, with salt and freshly ground black pepper. Set aside, covered, until needed.

3.     To prepare the pasta, dust the rollers of a pasta machine with flour. Cut the chilled pasta into three pieces and flatten each out to a thickness of about 1cm/½in.

4.     Set the pasta machine to its widest setting and feed one piece of dough through the machine, turning the handle with one hand and collecting the rolled dough as it comes through the machine with the other.

1.     Change the setting on the pasta machine to the next thickest setting, dust the rollers with a little flour, then feed the same pasta sheet through the machine again, as before. Repeat this process three or four more times, flouring the machine and changing the setting down each time, until you reach the penultimate setting. As your pasta sheet becomes longer, cut it in half so that the rolling process is more manageable.

2.     Repeat the rolling process with the remaining two pieces of dough. Once all of the dough has been rolled out, you should have six long sheets of pasta.

3.     To make the tortellini, place one long sheet of the pasta onto the work surface with the longest side facing you. Place two large basil leaves in the bottom half of the pasta, then fold the top half over the basil leaves. Set the pasta machine to its finest setting and pass the sheet through the machine again. Repeat the process with the remaining pasta sheets and large basil leaves.

4.     Cut the pasta sheets into 9cm/4in discs using a cookie cutter. Place one small basil leaf into the centre of each, and top with one teaspoonful of ricotta.

5.     One by one, brush the edges of each pasta disc with a little water. Bring the edges of each disc together to form a semi-circular shape, pressing the edges together with your fingertips to seal. Bring the pointed ends of the tortellini towards each other around your fingertip to form a ring, then press the corners together using your other hand.

6.     Repeat the process with the remaining pasta discs, basil and ricotta; you should end up with 20 tortellini.

7.     Bring a large pan of salted water to the boil. Carefully lower the tortellini into the boiling water, in batches, and cook for 3-4 minutes, or until they float to the surface of the water. Remove from the pan using a slotted spoon and set aside in a bowl, keeping warm. Cook the remaining tortellini.

8.     Add the pesto to the tortellini and mix gently until coated. Sprinkle over the pine nuts.

9.     To serve, spoon the tortellini and pesto onto serving plates. Sprinkle some grated parmesan over each and garnish with a few small basil leaves.

Including ricotta cheese in your diet boosts your calcium intake; one serving provides you 51% of the daily value. A consumption of ricotta cheese will also provide you with 39% of the daily value of phosphorus, 28% of riboflavin, 22% of vitamin A, 19% of zinc and 14% of the daily value of vitamin B-12. Amounts may vary in part-skim and fat-free varieties. Eating a portion of ricotta cheese also provides 7.5 g of carbohydrates and 27.7 g of protein. Both of these macronutrients contribute to your energy needs. Fat-free ricotta provides you slightly less protein and more carbohydrates than whole milk ricotta; part-skim ricotta has approximately the same amount of protein but more carbohydrates.

 

A cup serving of whole milk ricotta cheese contains 428 calories and 31.9 g of fat. The majority of that fat (20.4 g) comes from saturated fat, the type of fat that can wreak havoc with your blood cholesterol levels and lead to an increased risk of heart disease. There are part-skim and fat-free ricotta varieties available, even though the texture of the ricotta, normally creamy and sweet, may suffer. Part-skim ricotta has less fat and calories per serving, because 1 cup has 339 calories and 19.5 g of fat. Fat-free ricotta contains 160 calories and no fat.
