Marjoram is actually a pretty fantastic spice that doesn’t get the credit it deserves. It appears sporadically in European cooking, but it is most valuable in spice blending and advanced cookery. Marjoram is a very close relative of oregano (as you can tell by its botanical name), but has a smoother, lighter taste and aroma. which allows it to act as a “bridge” between sweet or tangy and robust or earthy spices. It is a wonderful ingredient in spice blends combining bright and warm flavors, and goes very well in slow roasted meats or vegetables, robust or spicy sauces and soups, or aromatic dressings and stuffing.
