This cinnamon comes from the Cassia Korintji grown in China, Vietnam, and Indonesia. Cassia is a substitute for real Cinnamon. Cassia is an aromatic bark, similar to cinnamon, but differing in strength and quality. Cassia is less costly than cinnamon and is often sold ground as cinnamon. Where cinnamon and cassia are differentiated, cinnamon is used for sweet dishes, or ones requiring a subtle flavor, and cassia for strong, spicy, main dishes. Cassia is often used in stewed fruits, especially apples and with mixed spices for pudding spice, pastry spice and mulling spices.
