Freezing whole strawberries I'd like to freeze strawberries for winter, I read online that a method is to sprinkle sugar on them and put into a zip-lock or plastic bag or an air-tight container. another method is to make ice cubes with them. I wonder what the cons and pros of each method is and if one is preferred over the other. and do you know any other methods? I also read about strawberries in simple syrup but I don't like the idea.
Okay. You don't want them to lose their shape or flavor when thawed. I don't know of any way that is possible. Fruits that contain a lot of water are going to be mushy when thawed. No matter how you do it. No exceptions.

The only suggestion I have for you is to maybe dehdrydate them for future use and then they can be rehydrated. That's not a great solution, just an option.
