there are 2 things you can do. i do it every year, i can about 50 quarts, use the Ball book or pm me and i can give you a detailed message on how to do it; you must pre cook. GREAT fried taters! i also mix them in oil, seasonings, parmesan, and bake on a cookie sheet. fantastic every one loves favorites. we also like hash browns. boil the taters till slightly underdone. then put in fridge overnite to cool and firm. grate them, i use a larger holed grater for this, spray foil with pam, put on cookie sheets in single layer, foil, single layer, etc, and freeze them. then you can just put them in ziplocks and voila! hashbrowns when you want them!
