How to Freeze Potatoes for Feedings

Here is the easiest way to always have potatoes on hand for feeding your starter.

Instructions

  • 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.
