cannot be eaten straight from the oak tree since they contain a lot of tannins
which make them test very bitter and also make them poisonous - however acorns can be processed into acorn flour
with a bit of work. Acorns contain protein, carbohydrate, and fat, together with vitamins and many minerals
; fortunately the tannins are water soluble so they are not difficult to remove.
Collect and Dry Acorns
Collect a big bag full of acorns making sure you leave behind any with small dark holes in them since they have been damaged by worms. Also return any acorns which float in a bucket of water since they also have bugs in them.
Put the good acorns in the oven at the lowest possible temperature with the door ajar to dry out the acorns and kill any insects you brought home with them. Then break off the shells and discard.
Grind the Acorns
Now the acorns
need to be ground up using either a food processor, a sturdy blender (with water), or a meat grinder if you are lucky enough to have one. The resulting mush of acorns needs to be rinsed many times in order to extract and remove all of the tannins
Put the mush into a piece of cheese cloth or muslin, and pour clean cold water
through it 2-3 times per day. Depending on the variety of acorn (and the amount of tannins in them) this process can take anything from a few days to a couple of weeks. Every day or two, take a tiny taste of the mush to see if it is still bitter. When it is no longer bitter, the tannins have leached out, and the acorn flour
is nearly ready. Don't keep on soaking the acorns once the tannins are gone, or you will lose some of the delicious nutty flavour that acorns have.
The tannin-less acorn mush now just needs to be thoroughly dried
. Spread it out on a tray and put it in a very low oven with the door slightly ajar, occasionally turning the acorns until they are dry. Your acorn flour can be stored in jars, and used in recipes in place of wheat flour.
Alternatively, if you have some freezer
space free, just squeeze the mush tightly with cheese cloth
to get rid of the vast majority of the liquid, and then freeze suitably sized portions in zip lock bags.
Cooking with Acorn Flour
It is best to include an equal measure of wheat flour
when using acorn flour, since acorn flour alone does not hold together very well. You can make delicious acorn pancakes
, acorn bread
, and acorn muffins
with this flour.
