Step 3. Place dark chocolate in a microwave-safe bowl. Heat in 30-second increments in the microwave. Repeat this process until chocolate is almost completely melted. Continue to stir until all of the chocolate is completely melted.
Step 4. Dip pecans one at a time halfway into melted chocolate. Tap lightly against the side of bowl to remove excess chocolate. Place dipped pecans on baking sheet and sprinkle with flaky salt (if using).
Step 5. Your chocolate should set in less than 5 minutes. If chocolate still hasn't set (hardened) by the time you are done dipping all of your pecans, stick baking sheet in refrigerator for 5-10 minutes.
