ok..
1 large can of Carnation (e.g. condensed milk--my *very* Southern family just calls it "carnation")
1.5 c. of sugar OR a can of Eagle Brand milk (e.g. sweetened condensed milk)
several cups of whole milk
1-2 teaspoons of vanilla
Mom said you just have to stir up the sugar (or SCM) really well with the other ingredients, starting with just a little milk and adding, tweaking, adding, tweaking until it tastes right. (I know that not helpful when you're looking for INSTRUCTIONS
but that's pretty much how the women in my mom's family cook) She said the liquid needs to taste a little sweeter than what you want the ice cream to taste like.
It's the kind that gets really solid near the walls of the container, and is very soft/light (almost like snow ice cream) near the center. It melts in your mouth but it's not creamy or heavy like store bought ice cream.
