If you want to make ice cream, you must melt Crisco, so slice the Crisco really thinly for this purpose.
Put all the sliced Crisco pieces in a pot, either non-stick or regular, and stir until they melt.
As you continue to cook your dish, make sure that the temperature is appropriate for your dish.
Continually stir the sugar into your melted Crisco, ensuring that all the sugar has dissolved.
Put some water in your liquid mixture and turn off the heat. This way it will slowly cool down and become fluffy.
A little more water can be added once you see it fluffy and turning white.
Stir all your mixed berries into the fluffy Crisco mixture. After that, place the container in the freezer in order to freeze it.
Taking the ice cream out of the freezer and allowing it to sit for an hour before serving will ensure it stays firm.
