No worries! You can create a double-boiler with a small pot and a heatproof bowl (I like stainless). Place the bowl over a pot with boiling water, being careful not to let the water touch the bottom of the bowl. Place the chocolate in the bowl and let sit 1-2 minutes, or until the edges begin to melt. Stir until almost smooth. Carefully remove from heat and stir until completely smooth.
