Not too sure about homemade ice cream, but usually crystallization is the result of the freezer being too cold.
Back in my day , guys like me and Vince Basille used the old hand crank to make our homemade ice cream .
It was hard work and the ice cream tasted like shit, but it was a good arm pump.
We lifted rocks at a real rock quary , ate real ice cream and didn't need steroids.
Those were the days
