I tried
this recipe and its good.
I did made changes on the amounts.
I used 1/2 cup milk
about 3/4 cups ice just because I like mine really icy.
about 1 1/2 tablespoons pudding mix
and syrups to my taste. I tried measuring but I kept adding more so I have no clue how much I used. It was less than a forth a cup but more than 2 tablespoons.
