Unsweetened chocolate or Baker's Chocolate is from a pure coco bean. Usually, unsweetened chocolate is only for baking purposes as it has a strong, bitter taste. Several types of recipes call for melting chocolate. You can also use the melted chocolate for decorations or for candy. The temperatures vary on different styles of microwaves. By carefully watching and frequent stirring, you can quickly melt squares of unsweetened chocolate in the microwave.
Break the squares apart from the bar of unsweetened chocolate. For quicker melting, break the squares in half or fourths.
Place the chocolate in the center of the small microwave-safe casserole dish. Spread out evenly so the pieces are level.
Put the dish in the center of the microwave. Press the medium or medium-high cooking setting. Start the timer at 60 seconds.
Stir the unsweetened chocolate after the 60 seconds has expired. Add another 30 seconds. At the end of the timer, stir. Repeat until the melted chocolate is the texture you desire.
