Requeijão is a milk-derived product, produced in Portugal and Brazil. It is a loose, ricotta-like cheese used to make cheese spreads. It can be a good substitute to mild, unsalty ricotta. This variety is sometimes sold in the markets wrapped in fresh corn husks. In El Salvador, cheeses such as requesón can sometimes be transported wrapped in banana leaves instead.
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 type of cream cheese white in color (but not similar to the American notion of cream cheese, and may be better understood as "cheese cream"). It has a mild taste and its consistency can vary from creamy solid, like the branded Catupiry, to liquid. Its most common variant is requeijão cremoso, with a consistency similar to that of condensed milk; usually sold in glass or plastic cups, both generally re-employed by Brazilians as regular cups.
Romeu-e-Julieta is a dessert that combines white cheese and guava paste. It usually calls for queijo minas, requeijão or ricotta, with requeijão generally being the one used in Brazilian-adapted pizzas, crêpes, waffles, pancake rolls and spring rolls.
