Completely melt the chocolate in the microwave or a double-boiler until it registers the temperature listed on either the packaging or the above table on a food thermometer.
Toss in the seed chocolate and stir until melted. Consistently fold and stir the chocolate to help cool it until a thermometer registers the recommended temperature on the packaging.
Using either the microwave or a double-boiler, gently reheat it to the recommended temperature on the packaging.
Test the temper by dipping an offset spatula into the chocolate. If it sets quickly and comes out smooth and shiny, it's ready to use!
