Orange Muffin is a fruit flavored muffin, made especially from orange juice or extract and grated orange zest, along with other basic ingredients that go into making muffins. Often made plain or in combination with other fruits and flavors like cranberry-orange muffins, chocolate-orange muffins etc, this variety of muffins are often garnished generously using walnuts, hazelnuts etc. Best enjoyed warm, orange muffins taste awesome with a little marmalade by the side.
