Is bulgar wheat and couscous interchangeable?

Bulgar wheat and couscous are not directly interchangeable, as they have different textures and flavors. Bulgar is made from cracked wheat and has a nutty taste, while couscous is made from semolina flour and has a lighter, fluffier texture. However, they can be used in similar dishes, such as salads or grain bowls, with adjustments to cooking times and methods. Substituting one for the other may alter the final dish's taste and consistency.
