Should shortening be added when melting chocolate chips for dipping?

No, you shouldn't add shortening to chocolate chips when melting them for dipping. Melting chocolate chips with shortening compromises the chocolate's taste, texture, and appearance due to the different melting temperatures of the two.

Chocolate chips are primarily composed of cocoa solids and cocoa butter. They melt at around 34°C (93°F). On the other hand, shortening is a type of solid fat typically made from vegetable oils. It has a higher melting point than chocolate, usually around 37°C (99°F).

So, when you add shortening to chocolate chips and try to melt them together, the chips melt faster than the shortening. This results in an uneven melting process. You'll end up with a mixture where some chocolate chips are fully melted, some partially melted, and the shortening remains unmelted.

This affects the texture and appearance of the chocolate chips. Because shortening doesn't melt smoothly like chocolate chips, your mixture might become grainy, gritty, or even crumbly instead of smooth and velvety.

The flavor can also be affected if you use shortening. Shortening has a neutral taste, so it doesn't enhance or complement the chocolate's flavor. Instead, it dilutes it, making the chocolate taste blander and less rich.

Here are a few tips for melting chocolate chips effectively for dipping:

1. Microwave Method: Place the chocolate chips in a microwave-safe bowl. Heat in short bursts of 15-20 seconds, stirring in between, until the chips are mostly melted.

2. Double Boiler Method: Fill a large saucepan with about an inch of simmering water. Place a smaller heat-resistant bowl over the saucepan, ensuring the bottom doesn't touch the water. Add the chocolate chips to the smaller bowl and stir constantly until completely melted.

3. Direct Heat Method (Advanced): If you're experienced in controlling heat and have a good heat-proof bowl or pan (ideally with a thick base), you can try melting the chocolate chips directly on low heat on the stovetop. Stir continuously and remove the bowl from the heat source as soon as the chips start melting.

Remember to keep the heat low and stir consistently throughout the melting process to ensure even melting and prevent scorching. If you add shortening, you won't achieve a smooth and glossy consistency, which can hinder the chocolate's ability to properly adhere to whatever you're dipping.
