Analysis of information sources in references of the Wikipedia article "Sage Derby" in English language version.
SAGE CHEESE: is made by the Cheddar process and in many shapes and sizes. Its distinguishing characteristic is the flavor of sage and its green mottled appearance when cut. The color is obtained either by mixing green sage leaves in the curd before pressing, or by the addition to the main curd of "green curd" obtained by the aid of the juice of green corn—in the latter case, the sage flavor being obtained by the use of sage extract. Parsley, spinach and marigold leaves, bruised and seeped before use, are sometimes employed in place of sage leaves
