How to Grind Flax Seeds at Home

Grinding flax seed at home needs no special equipment, just a small grinder and a habit of doing it in small batches, since ground flax does not keep as well as the whole seed does.

How to do it

A small coffee or spice grinder works well for flax seed, pulsed in short bursts rather than run continuously.
Grind only what you expect to use within a week or two, since ground flax oxidises faster than whole seed.
Store the ground portion in an airtight container, ideally refrigerated, to slow that process further.
A mortar and pestle works for small amounts if you do not have a grinder, though the result will be less uniform.
Roasted seed grinds a little more easily than raw, if you have the choice and want a smoother result.

One household compares whether roasted or plain seed keeps longer once ground in small batches, useful if you are deciding which to keep on hand for grinding.

Grinding flax questions

Can I use a regular blender to grind flax seed?: A small dedicated grinder works better for a small quantity. A large blender can struggle to grind a small amount evenly.
How much flax seed should I grind at once?: Enough for a week or two of use is a reasonable batch size, balancing convenience against freshness.
Does grinding release the oil inside the seed?: It exposes it to air, which is part of why ground flax should be stored carefully and used relatively soon.
Is store bought ground flax as good as home ground?: Home ground in small batches is generally fresher, since you control exactly when the grinding happens.
