This is a very versatile combo and a must for every kitchen. Oregano is generally described as possessing a strongly aromatic camphoraceous aroma and a slightly pungent flavor. This pungent flavor is composed of earthy/musty green hay and minty notes. The spice imparts a slightly astringent mouthfeel. Which tastes more like chili peppers? Crushed red pepper takes the crown here but it's not because of their distinct hot pepper taste. In fact generic red pepper flakes don't have too much of a flavor – slightly sharp and a little earthy with a decent dose of spicy.
