Matiz cooks tart Spanish quince in sugar for hours to create their heavenly dulce de membrillo paste, a specialty fruit preserve with a versatile tropical flavor. Sweet, sour and tangy all at once, quince paste is reminiscent of pineapple or guava jams. This artisan condiment pairs beautifully with Manchego cheese, bread rolls, pastries and even grilled steak and porkchops. Matiz is a world-renowned producer of gourmet Spanish foods.
