I think most of us have tried our hands at dehydrating of some sort. I have a relatively cheap dehydrator (around $30-$40), but it works. You can get a super expensive and fancy one with timer and heat adjustments or you can even use your oven on a very low temperature. Many use the sun and air like back in the days of our ancestors.
I have been drying tomato skins and scraps for years. I dry and make a powder which is great in my seasoning mixes and it is good to add extra flavor and nutrients to things like soup. I dry my herbs (mainly air dry those). I have even dried those big old bottom cabbage leaves that most people trash. I dehydrate and powder them and then add to soups for extra nutrients.
There truly isn't much that can't be dehydrated and turned into a powder.
WHY? you may ask.
Well it is a good way to not waste anything. It is a great way to add flavor to things. It is a great way to get fruits and veggies into those who won't eat them fresh or cooked!
You can dehydrate not only veggies of all sorts but fruits as well.
FRUITS - any berries - berries work great for turning into powders. You can dehydrate ALL fruit and use in various ways.
Use powdered berries/fruit with oatmeal, yogurt, in milk or over cereal. Make a fruity flavored salad dressing (those are pricey to buy), use in sweet breads and muffins, cakes, cookies and even pancakes and syrup! Use over ice cream or pudding.
Make fruity cream cheese dip, your own fruit sugars, use in tea, smoothies and even cocktails.
Make your own flavored gelatin - use unflavored gelatin and whatever dried fruit powder you want.
You can just make so many fun and nutritious goodies.
VEGGIES - Anything goes. Tomato skins, greens of all sorts, onions and scallions, mushrooms, garlic, broccoli stems, absolutely anything you can think of.
You can add to smoothies and soups and casseroles.
You can make your own seasoned salts (onion salt, garlic salt). Make your own dips and flavored cheese balls
Add to anything that is savory
HERBS - add to dips, soups, seasoning mixes. Things like lemon balm and mint can be added to teas and smoothies as well
I have even drained and dehydrated older homemade pickles and peppers that I have canned (and no longer crunchy). Blend them into a powder and you have great seasoning to add to dressings and dips.
I also dehydrate extra large okra from the garden - dry and grind - it makes a fantastic natural soup thickener without adding any taste.
FIRST you want to dehydrate and dry completely!!!!!! IMPORTANT
Use a coffee grinder or blender to grind to a powder. May need to do this a couple times.
You want to store in glass or plastic JARS that are airtight.
To be extra sure they last well - add a desiccant pack to each jar to absorb moisture.
You can also mix in 1 teaspoon of arrowroot powder to each pint (no taste change) to keep things from clumping.
Most fruit and veggie powders last a year if kept tightly sealed.
This can be such a fun project. Just think about everything you grow and buy in the produce arena - and then dehydrate some of it. Nothing goes to waste. You have a great new seasoning. You are getting extra nutrients and vitamins into your diet.
Use your imagination - have fun and waste not!
