If you grow your own garden, or even if you just know how to frugally purchase your produce, then there is no need for you to spend a lot of money on your spice rack.
Here’s how you can easily make your own onion powder and onion salt for pennies.
The first thing you will need to do is dehydrate your onions. I use white onions for all of my dehydrating needs. I have never tried this with my yellows or sweet purples. Click here to see how I dehydrate onions every year.
If you let your onions cure before dehydrating them, then you’re ready to make your mixes. If not, place in a freezer bag in your freezer for 2 weeks or more.
Make sure you have something to store your new salt and powder in. You can use old spice bottles if you want. I always keep the glass ones, and occasionally someone gives me their old glass ones. I never throw them away.
If you want to make a bigger batch (since that really is the easiest way to go), then grab an appropriate sized canning jar. You can dry can a bigger batch (this is what I do), or use these lids for your jars. When all else fails, small peanut-butter lids fit regular sized canning jars.
Carefully place your dried onion in a small chopping appliance with the lid on. Turn on until you’ve got a fine powder. Leave the lid on until the powder settles. Taking it off immediately will probably result in a fine onion powder in your face.
If you want onion powder, you’re done. Pour into your bottle (using a funnel if you have one) and you’re done.
If you want onion salt, mix three parts table salt with one part onion powder. Mix well, and pour into your bottle (again, using a funnel if you have one).
Label and store as you normally would.
