Dulce de membrillo (or just membrillo) is a sweet, sticky, very thick jelly made from the fruit of the quince tree, and is a typical dessert eaten in Spain, although it is also served with toast at the breakfast table. Unlike the jellies we are used to eating in the US, membrillo is dense enough to hold its shape. Dulce de membrillo has a sweet flavor tinged with a bit of sharpness and is similar to guava paste in both appearance and taste. In English, it is known as either quince paste or quince cheese. Best paired with salty, buttery cheeses such as Manchego.
