Tempering chocolate is about guiding cocoa butter to form stable beta crystals, which give chocolate a glossy surface, crisp snap, and good storage stability. The marble slab (table) method combined with seeding is a classic and reliable way to achieve this. In the marble method, you melt the chocolate to a high temperature to melt all crystals, then spread it onto a cool surface like a marble slab and work it with a scraper. The rapid, even cooling on the cool surface promotes the formation of stable crystals as you move the chocolate around. When it reaches a lower, working temperature, you scrape and gather it back together and warm it slightly to keep it fluid for molding or dipping. Seeding adds small pieces of already tempered chocolate into the melted mass, providing nucleation sites that steer the crystallization toward the stable forms and help the rest of the chocolate crystallize correctly.

The other options don’t temper chocolate. Cooling in the refrigerator is too rapid and often introduces moisture, which can dull the finish and cause bloom. Whipping with air doesn’t influence the crystal structure needed for tempering. Steaming introduces moisture and can cause the chocolate to seize.
