Re-Hydrating Dehydrated Food

When re-hydrating dehydrated food, in the images below, you can see the water being absorbed and just how far up the jar the vegetables in the water have risen!

These dehydrated vegetables are from previously frozen bags of crinkle-cut carrots, peas, and green beans. There are also some Ore-Ida Hash Brown potatoes in there—along with dehydrated fresh onion, celery, and elephant garlic!

Note: You now have the humble/great beginnings of a very tasty Vegetable Soup.

The magic of rehydrating food! It's fun to watch it plump back up!

Re-Hydrating Dehydrated Food

This is the AMAZING PART! Hopefully, you've learned a lot from our site about how to dehydrate your foods, so now it's time to put the water back in and rehydrate dehydrated food!

Make Sure To Add Enough Water!

Add Enough Water!

For a cupful of dehydrated veggies, for instance, I'll add water to the 2-cup mark in a glass measuring jug.

Add twice the amount of water to the amount of food you are rehydrating.

It's really only a case of making sure there's enough water for the foods to drink up while rehydrating food.

Keep your eye on the food. Add more water if it looks like it'll dry up before your foods are nice and plump again!

Should I Use Hot or Cold Water?

I'll use hot (boiling) water for re-hydrating food when I'm making a recipe that calls for hot 'stock' because my bouillon dissolves better in just-boiled water—but if you know it'll be sitting around a while before you get to use it, then cold (clean) water works fine.

I must make an important point here: if you are rehydrating food in hot water, please make sure to BRING IT BACK TO A BOIL while you're preparing your recipe.

You don't want to have food sitting around in warm water without boiling it again—be safe—don't let any airborne germs get a chance to fester in "warm" food prior to eating it!

It takes about an hour for small veggies to plump back up in the water; the larger veggies take longer, about two hours.

Also, note that you may want to cook your rehydrated veggies a little longer than usual... it helps make the vegetables taste like whole vegetables again.

Water Quality Counts when Re-Hydrating Dehydrated Food

Remember, the quality of the water you use while re-hydrating dehydrated food IS important, as the water is being absorbed by the foods that you are going to eat re-hydrated again—so don't skimp here by using nasty water! By nasty, you know what I mean! If you wouldn't drink it, don't use it! Make sure it's good, clean, drinking water.

It's not always necessary to rehydrate your foods. For instance, grind up some of your dehydrated garlic to make garlic powder, and grind up some dehydrated onions too for onion powder! Don’t forget dehydrated celery for celery powder (add a little salt for celery salt).

If you're making a soup where the vegetables aren't sautéed in olive oil at the start of the recipe, then go ahead and just add them to the water (or soup stock or soup base according to the recipe) in their dehydrated form!

They'll plump right up in the water/stock base if you let them sit and cook long enough! Shredded dehydrated cabbage is another vegetable that is great tossed in soup while you're making a pan!

What About Nutrients?

Melba, a good friend of mine, asked me if dehydrated foods lose their nutritional value and how did they really taste when rehydrated.

Excellent questions Melba! I assured her they keep much of their nutritional value because all that's been taken out is the excess water during the dehydration process... (but like ALL fruits and vegetables, when overcooked, they WILL lose nutrients!)

And the Taste?

I will admit that my first effort at rehydrating carrots yielded somewhat spongy carrots, but when I cooked them a little more, they were fine. They were whole baby carrots and that might have had something to do with the sponginess.

My sliced carrots rehydrated perfectly! All the other vegetables just come back to life when added to water and it's really quite amazing to see! My favorites are peas and celery! The grated carrots in the above photos were for Deb's Delectable Carrot Cake—check it out, it's delectable, alright!

Take a look at Preparedness Advice—they have a good chart on how much water to use when rehydrating your dehydrated foods.

What's a "Normal Portion Size?"

Audrey just wrote in to ask, "Susan, what's a normal portion size of dehydrated carrots?"

Great question Audrey! First, thanks for taking the time to write in.

For a personal portion of carrots, using dehydrated carrots, I'd say a "couple of handfuls" would be enough. Carrots shrink down to at least half their normal size, so just look at a couple of handfuls (assuming you don't have massive hands LOL) and imagine those handfuls to be double that when they're re-hydrated.

I hope this helps, and thanks for asking!
