Grated zest is simply the grated rind (outer colored portion) from citrus fruits. It is used in cooking because the rind holds the precious oils where the entire flavor resides. To grate zest or rind, take a box grater and rub the fruit against the grater. Don't rub the fruit down to the white inner skin, known as the pith, because the pith is bitter. When removing the skin from oranges or other citrus fruit, be sure to take only the thin outer zest or colored portion. The white pith will give your dish a bitter undertaste.
