This is a DIY sauce mix for scalloped potatoes (aka Dauphinoise potatoes.)
Use it with your dehydrated potato slices.
Just add water, pour over the dried potato slices, and bake.
To be clear, this is NOT a canning recipe. Don’t attempt to can the scalloped potatoes, and don’t attempt to even dry-can this mix: the heat would shorten the storage life of the powdered milk in the mix.
Double or triple recipe if desired.
Yield: Makes 600 g / 4.5 cups. Enough for 9 batches of scalloped potato.
Use ½ cup (75 g / 2 ½ oz) per batch.
