White chocolate can be easily tempered at home. Using Purdys Classic White Chocolate Bar, pack of 9, 360 g, chop the chocolate bars fine. Reserve 1/3 of the chopped chocolate. For the rest, place in a microwave-safe plastic bowl and heat in the microwave 20 seconds at a time, stirring in between each burst. Do this until the chocolate is fully melted. Add in the reserved chocolate pieces and stir until smooth, and your chocolate should be in temper. Be careful to heat in short bursts and to stir frequently – white chocolate is delicate and can be prone to burning.
