What is the average serving temperature range for soft-serve ice cream?

The average serving temperature range for soft-serve ice cream typically falls between 18°F to 22°F. This temperature range is ideal because it keeps the ice cream soft enough to be dispensed easily while also maintaining its structure and preventing it from melting too quickly. Serving it at this temperature enhances the texture and mouthfeel, allowing for a creamy, enjoyable experience that many consumers expect from soft-serve.

The other choices propose temperatures that are either too low, which would make the ice cream too hard and difficult to serve, or too high, which would result in a melted product that alters the intended serving quality and experience. Therefore, the selection of 18°F to 22°F is scientifically and practically established as the best serving temperature range for soft-serve ice cream.
