Spread vegetable bouillon out onto a parchment-lined baking sheet for dehydrating in an oven. Or spread on a silicone mat-lined dehydrator rack for an electric dehydrator.
Place baking sheet (or sheets) on an oven rack in a 175°F preheated oven. Or place the dehydrator rack into a dehydrator and set the temperature to 125°F.
Periodically check the vegetable bouillon as it is drying. You may want to break up any clumps that appear damp. It will take approximately 6 hours in the oven and 10 hours in the dehydrator to dry fully.
IMPORTANT: You must make sure that your vegetable bouillon is VERY dry before moving on to the next step. You will know that it is very dry because you will not be able to form clumps if you squeeze some in your fist. It should simply crumble into a fine grain, like salt.
You can crumble the dried vegetable bouillon in your hands. However, the most efficient way to turn your dried bouillon into a powdered form is to grind it in a small grinder or blender. This process will take approximately 30 seconds.
Store the vegetable bouillon powder in a jar with a lid. You can now store your powder in a pantry, and the powder should have a shelf life of approximately six months to one year.
To reconstitute the vegetable bouillon powder, use 1 teaspoon per 8 ounces of hot water.
