If a Belgian endive head exhibits significant greening, what does this usually indicate about its growing conditions?

Answer

It received too much light during the forcing stage

When selecting Belgian endive, the color is a key indicator of proper cultivation and flavor profile. A creamy white to pale yellow hue is desirable. If a head shows significant greening, this signifies that it was exposed to light at some point during the specialized forcing stage. Light exposure triggers chlorophyll production, turning the leaves green. In the context of endive, this deviation also correlates with an increased concentration of the bitter compounds that the forced blanching process is specifically designed to minimize, resulting in a flavor profile potentially more assertive than intended.
