Together, let's go over
the things you will need: * 1 large sterilized glass jar with lid * 1 opaque large sterilized glass bottle with cap (we'll talk about sterilizing in a moment) * Fresh stevia leaves (although you can also use dried leaves, please read tips at the bottom) * Vodka * Funnel * Cheesecloth (or a coffee filter) for sieving * Saucepan
The first thing to do on your way to making your own stevia extract, is
to sterilize your jars
and lids, by first
rinsing them thoroughly in hot water to clean them, removing any labels
in the process. When you're done, put
the wet jars and lids upside down into the oven (300°F/150°C) for about
10
minutes until they are dry.
After buying dried stevia
leaves - or, preferably, growing your own stevia
plants and using fresh leaves - remove the brown parts and
the stems and crack or tear up the
leaves. Always keep in mind that only the leaves
contain glycosides (stevia's sweet elements), so don't waste your time
on the other parts.
Put the stevia
herb
in one of the sterilized jars, filling it all the way
up
to the rim. Pour over the vodka until the jar is full and all of the
leaves are saturated - the alcohol in the vodka is going to extract the
glycosides from the leaves.
Twist the lid onto the jar
and put it in a cool and dry place, letting it steep for about 36
hours. For the best results, don't let the leaves steep for longer than
that because the longer you let them soak, the more bitterness will be
extracted... We're going for sweet stevia extract, after all!
Shake the jars gently from time to time.
When the time is up, put
the funnel in the opening of your sterilized
bottle and cover the funnel with a piece of cheesecloth or with a
coffee filter. Gently pour the contents of the jar in the
funnel, and let the extract - it should be a brownish color - slip
through to the bottle below. Continue pouring until all the liquid is
transferred from the jar to the bottle and at the end, gently press the
pulp down that's left behind in the funnel in order to extract the
final drops.
When you have collected
all of the tincture, transfer it into a saucepan. Heat the liquid over
a low fire, making sure that it never
gets to a boiling point! If your liquid starts to boil, it
will scald the glycosides and your extract will be ruined. The alcohol
in the vodka will
evaporate pretty quickly, and you will be left with a syrupy brown
liquid. The longer you heat the mixture, the thicker it will become.
Generally the heating time should be somewhere between 15 and 30
minutes.
If
your stevia tincture is
too thick, you can dilute it by adding some water to it and stirring
well; this dissolves some of the steviosides. Transfer the extract to
an opaque bottle with a tightly screwed on cap. Shelf life is about three months in the
fridge. Congratulations! You've just made your first batch of stevia
extract!
