Difference in texture when frozen
This annoys me and I just hope someone can explain this to me. I regulary buy ice coffee at the store and put it in the freezer. The ice coffee consist of mostly milk and coffee. When I defrost the frozen ice coffee for half an hour in a glass of water it turns into a smooth, frozen, creamy beverage to enjoy with a spoon. Major life hack if you ask me.
BUT – sometimes the same ice coffee has a completly different texture after freezing. Happens about 1/4 of the times. It becomes icy and flaky and crunchy – not a desired consistency. I cant seem to find the reason for this happening. I’ve considered testing different things – using the super freeze mode on the freezer vs not, shaking the beverage before freezing vs not. But instead I would love if someone could just explain the chemistry behind it 😅
In: Chemistry
I think stirring vigorously before freezing might bring about the result you desire.
What is happening is you have a complex mixture of emulsified solids. The size of those particles is critical to the behavior of how they freeze.
