Blanching primarily removes what from bones to prevent cloudiness in stock?

• A. Impurities
• B. Fat
• C. Salt
• D. Color

Answer: (D)

The main idea is that stock clarity comes from removing particles and proteins that would cloud the liquid. Blanching bones briefly in hot water helps lift away surface impurities—blood, coagulated proteins, and other small bits from the bone and connective tissue—before the stock is made. By rinsing or discarding this first blanching water, you prevent these soluble impurities from leaching into the stock, which keeps it clearer as it cooks. Fat can separate and be skimmed later, but blanching isn’t aimed at removing fat; salt isn’t affected by this step, and color isn’t the primary issue here—the cloudiness comes from the impurities that blanching helps wash away.
