You can grind 1 tablespoon (14.8 g) in less than 30 seconds.
- In addition, you can use a mill to easily top a smoothie or salad with ground flaxseed.
- If you do not use flaxseed regularly, it may not be cost-effective to invest in this device.

Use a spice grinder or pepper mill for an inexpensive option. Remove the top of the spice grinder and pour in about 1-2 tablespoons (14.8-30 g) of flaxseed. Replace the lid and crank the handle for 1-5 minutes until the flaxseed is ground to the desired size.^{[1]XResearch source}

Try using a mortar and pestle to finely grind your flaxseed. With this method, you can grind 1 tablespoon (14.8 g) to 1 cup (236.6 g) at a time. Pour the flaxseed into the mortar, which is the bowl-shaped object. Then, swirl the pestle (the hand-held grinding tool) around the mortar to mash up the seeds.

Question
Why are almonds soaked and skins peeled?
Community Answer
Because it is easier to peel when they're are soaked. The skin causes constipation, so that's why they're peeled.

Question
I'm not able to grind the seeds with a pepper mill. They are too light and don't fall into the grooves. Using a blender takes forever. Any advice?

If you have a coffee grinder around the house, this is a fast and easy way to grind flaxseed. You can also try a mortar and pestle for an easy way to grind your flaxseed by hand. Both are rather inexpensive options if you want to purchase a device to help you grind flaxseed.
