Instructions

    • 1

      Harvest stevia in the late fall, before the first frost or as soon as the blossoming begins, when the sweetener is at its strongest.

    • 2

      Cut the branches with pruning shears. Leave 1/3 of the plant's foliage so it may continue growing the following season.

    • 3

      Strip the leaves from the branches.

    • 4

      Dry the leaves on a screen or net. Leave them outside in full sunshine for 8 to 10 hours. Alternately, use an electric dehydrator on low (100 degrees F to 110 degrees F).

    • 5

      Stop drying when the leaves are crisp, crumbly and bright green. Avoid overdrying (the leaves will lose their sweetness).

    • 6

      Crush the dry leaves by hand or with a coffee grinder or herb blender.

    • 7

      Keep and use the herbs in their crushed form or make liquid stevia extract.

    • 8

      Add 1 cup of water to 1/4 cup crushed leaves. Let it set for 24 hours; pour the extract into a jar. Keep it refrigerated.
