Timing Is The Key To Keeping Ice Cream Frozen In A Cooler - Tasting Table
Briefly

To successfully keep ice cream frozen outdoors, it's essential to pre-cool your cooler, enhancing its insulative properties. A cold cooler ensures that ice cream retains its creamy texture and prevents melting. Using dry ice is an effective but potentially hazardous option. For standard coolers, chilling them in the freezer is recommended, while larger coolers can use big ice blocks or bags of ice. Packing the cooler tightly with other frozen items minimizes air flow and helps maintain the low temperature more effectively for at least four hours.
To ensure your frozen treats maintain their shape while outdoors, a cooler alone won't suffice; pre-cooling it and time are essential for optimal results.
Just as a thermos keeps soup hot through pre-heating, pre-cooling your cooler before adding ice cream is crucial for maintaining perfect texture and temperature.
