Introduction to Freeze Drying Potatoes
Have you ever considered freeze drying potatoes? Whether it's the regular type or sweet potatoes, freeze drying is a handy method that can help you extend the shelf life of these staple foods. This method is particularly beneficial for preserving homemade mashed potatoes.
Benefits of Freeze Drying Potatoes
Freeze drying potatoes, including sweet and mashed, not only saves space and time, but also makes meal times super quick! The best part is that they retain their original taste and texture, and all you have to do is add a little hot water to rehydrate them.
What You Need to Freeze Dry Potatoes
The main equipment you need to freeze dry potatoes is a freeze dryer. These machines make the process much easier and more efficient, allowing you to have shelf-stable, instant mashed potatoes at your disposal.
Preparing Potatoes for Freeze Drying
To prepare your potatoes for freeze drying, you need to start by cooking your potatoes. Choose your favorite mashed potato recipe, make it as directed, and let it cool.
Detailed Steps to Freeze Dry Potatoes
The process of freeze drying potatoes is not as complicated as it might seem. Whether you are working with regular, sweet, or mashed potatoes, the steps are similar.
How to Freeze Dry Mashed Potatoes
Start by spreading your cooled mashed potatoes onto a clean freeze dryer tray. It's important not to overfill the tray, as this could hinder the freeze drying process. Set your freeze dryer to run an entire course before checking if the potatoes are completely dry. If unsure, you can add more dry time. Once completely dry, break them up and pack them into a clean jar with an oxygen absorber or into a mylar bag for maximum storage time.
How to Freeze Dry Sweet Potatoes
Freeze drying sweet potatoes follows the same process as regular or mashed potatoes. The only difference is that you need to cook your sweet potatoes before freeze drying them, just like you would with mashed potatoes.
Tips to Ensure Successful Freeze Drying
To ensure successful freeze drying, avoid tightly packing the mashed potatoes on the tray. The dense nature of the dish can prevent the freeze dryer from fully extracting all the water. Also, never process more than a total of 5 pounds per batch, as this could lead to ice build-up in the freeze drying machine.
Rehydrating Freeze Dried Potatoes
To rehydrate your freeze dried potatoes, you can use water, milk, cream, half-and-half, or even chicken or vegetable stock. The choice of liquid depends on your preference and the specific type of potato you're rehydrating.
Rehydrating Freeze Dried Mashed Potatoes
Start with a ½ cup of liquid for 4 cups of freeze dried mashed potatoes. Add it gradually to avoid ending up with potato soup. Taste and add extra butter, salt, or even sour cream if you desire.
Rehydrating Freeze Dried Sweet Potatoes
Just like mashed potatoes, you can rehydrate freeze dried sweet potatoes with your choice of liquid. Remember to add the liquid gradually and adjust to taste.
Frequently Asked Questions about Freeze Drying Potatoes
One common question about freeze drying potatoes is whether you can freeze dry raw potatoes. It's not recommended to freeze dry raw potatoes without blanching them first as they can oxidize and appear unappetizing.
