How to Freeze Potatoes for Feedings
Here is the easiest way to always have potatoes on hand for feeding your starter.
Make plain mashed potatoes (no salt, butter, or milk).
Let cool to room temperature.
Portion into 1/4 cup servings using silicone molds or ice cube trays.
Freeze, then transfer to labeled storage bags.
Store for up to 3 months.
To thaw and use:
Place 1 frozen 1/4 cup portion into 1 cup of hot water until thawed.
Add 3/4 cup sugar, stir well, and let cool to under 100°F before feeding starter.
Bonus Tip: Thaw overnight in the fridge and mix with warm water the next day.
