Well, I am certainly making use of the dehydration button on the ninja….
The Mister is a funny being !
He like the taste of onions , but not the texture of them ( I know I have said that before ).
So when I am cooking anything that requires onions that we are both going to be eating I have to use onion powder.
This, I buy in small jars, you get around 40g in each jar.
I don’t mind doing that….but …what I do mind is the fact that the powder gets so hard very quickly after the jar has been opened.
So, I have decided that i am going to make my own onion powder and keep it in a zip lock bag.
Onions are on special offer this week so I bought a couple of bags.
I have sliced half the onions in one of the bags and I have them in the ninja as I type.
I’m not really sure how long it will take for them to be nice and crispy , I will play that by ear.
Anyway, fingers crossed this home made onion powder will stay as powder and not become as solid as a rock !

I kind of wish I had a dehyrator but if I really want to dehydrate something, I use the oven.

It’s a function on the ninja air fryer. I’ve found it so useful recently.

Thank you. I hope so too. I’m fed up of the shop bought becoming a solid lump after just one use.

I will try garlic if the onion powder is successful

Onion powder does not like moisture. Never, ever shake it over a hot, steaming pot. Shake it into your hand, or into a small dish, etc. When you shake it over a steaming pot, it gets moisture in it immediately which causes it to be hard. Also, if you freeze or refrigerate it in a container with a tight lid, that helps keep it from getting hard, too.

I think it just grabs moisture out of the air whatever you do. The only solution is to not open the jar and keep it with the rest of the herbs and spices as decoration.

I always tipped it onto a spoon before adding it to food. I will try keeping it in the fridge . Thank you for that tip.

I love onions and have them in as many meals as I can, except dessert of course. That would be weird! I’ve tried bought onion powder, but it always turned to stone before I even used half a jar, so I don’t bother any more.
