Requeijão is a milk-derived product, produced in Portugal and Brazil.
The Portuguese product is white to yellowish-white, solid, and usually having a characteristic strong taste; typically sold in specially designed draining plastic or basket-like weaved containers, or in plastic cups.
The Brazilian product is a cream cheese white in color, has a mild taste and its consistency can vary from solid to creamy. Traditionally associated with the state of Minas Gerais, nowadays it is produced all over the country. Its most common variant is requeijão cremoso, very creamy in consistency; usually sold in glasses or plastic cups.
Skim milk is held until lactic acid bacteria acidify and coagulate its proteins. The curdled milk is stirred and heated to a temperature as high as 80 °C (175 °F), then the whey is drained off and the curd is gathered in bags and pressed. The curd is placed in flat pans, broken up, and washed with warm skim milk, to form a mixture consisting of two parts milk to one part curd. This mixture is stirred and heated, as before, until the casein in the milk curdles and adheres to the mass of curd. The steps of draining, pressing, adding more skim milk, and heating are repeated once more. The curd is drained again, salted (2 to 2.5% by weight) and kneaded on a table for about 15 minutes. Hot butterfat or rich cream is added, about one part of butterfat for every five parts of curd, and the mixture is once again heated and stirred. The cheese is then molded in parchment-lined boxes.
About 11 kg of cheese is obtained from 100 kg of skim milk and 3.4 kg of cream. Composition varies, but a typical cheese can contain 55–70% water, 8–20% fat, and 16–20.5% protein.
