To make tempered chocolate, chop the chocolate into pieces and place 3/4 of it in a small glass bowl in a microwave for 20 seconds exactly. Stir the chocolate and continue to microwave for 20 seconds at a time, stirring in between, until the chocolate is smooth and shiny. Add the remaining 1/4 of the chocolate and stir until smooth. The chocolate should register 87 to 89 degrees F on a candy thermometer.
Dip each strawberry into the tempered chocolate and place on a sheet pan covered with parchment paper. Refrigerate for 2 minutes to set.
