Based on the provided reference, you can add a pinch of something (unspecified in the text) to chocolate melts to make them smoother.
The reference suggests adding a "pinch at a time" to the candy melts to achieve the desired consistency. It also advises against stirring and recommends using the "quick defrost" setting on a microwave. Unfortunately, the reference doesn't explicitly state what substance to add. Therefore, I can't give a more precise answer. Other common additions to chocolate melts to make them smoother are:
- Vegetable shortening (like Crisco): This is a very common addition.
- Coconut oil: This adds a subtle coconut flavor.
- Paramount Crystals: These are specifically designed for thinning candy melts.
