Question: are marjoram and oregano the same thing?
Answer: Oregano plants have a concentration of the aromatic compound carvacrol, which gives it its savory flavor. Marjoram, by contrast, is sweeter, as it isn't high in carvacrol. Instead, it gets its flavor from a variety of aromatic compounds including sabinene (fresh, woody), terpinene (citrus), and linalool (floral).
