How To Temper Chocolate To temper 1 1/2 pounds of bittersweet or milk chocolate, set a large bowl over a pan of simmering water. Add 1 pound of coarsely chopped chocolate to the bowl and stir occasionally until melted and an instant-read thermometer registers between 112? and 118?. Remove the bowl from the pan. Add the remaining 1/2 pound of chocolate and stir until melted and the thermometer registers between 88? and 90?. Use immediately.
