Notes
This ice cream takes a little planning as the ice cream base needs to be cooled after cooking. I also like to let the ice cream harden up in the freezer after it has been processed to make it more scoop-able.
You can enjoy it straight out of the ice cream maker but it will have more of the consistency of soft serve ice cream.
You can add in any type of berry you like using this ice cream base. Try a combination of berries for even more great flavor.
