Sour cream is so rich and full of flavor that it’s almost always a staple in baked goods, dips, soups, and sauces. Unfortunately, running out of sour cream stock is expected if you’re in a family who loves to cook and eat. Hoarding the cream is difficult, especially if you have limited fridge space.
But there is a way for you to stock up on the condiment without the need for cool storage. We’ll teach you how to freeze dry sour cream so that you always have a “secret” supply when needed. The best part? It won’t spoil on you even if you keep it in your room or take it with you when you travel.
Here are the suggested materials that you can use to make freeze-drying easier
Some prefer to use ice cube trays instead of spreading the cream on the trays. This is because you create more surface area by forming the sour cream into ice cubes.
Pre-freezing sour cream for freeze-drying is an option. But it does help shorten the freeze-drying cycle and makes your system convenient. If you have something going in your freeze dryer, you don’t have to wait for it to finish before you prep. Once the freeze dryer’s done, a few minutes of pre-cooling is all you need to start the process.
When you pre-freeze, use the freeze dryer tray for convenience. If you’re going to spread the cream all over the tray, use the spatula for an even spread. After spreading, you can use the dividers. As for the silicone tray, it’s optional for this method.
If you’re going to use the ice cube trays, remember to freeze the trays as well. You don’t want to melt the cream. Putting a warm tray in the machine will also cause a sudden change in temperature that can prolong the process. Squeeze out the cubes of frozen cream on the tray, leaving a small space in between. You don’t need large spaces because the cream doesn’t expand.
You can now prep the machine when you’ve got your frozen cream ready.
The length of freeze drying will depend on several things.
A huge spread of sour cream on the tray will take as long as 36 hours to freeze dry. But, if you made frozen cubes, 16 hours would be suitable for pre-frozen cream.
If you didn’t pre-freeze the condiment, freeze-drying could take up to 46 hours.
The sour cream should be dry, crumbly, and have a flakey consistency similar to mica decorations. If an area or cube feels soft, moist, and cool, put the tray back and add extra drying time. About 2-4 hours would be good, depending on the level of moisture left on your condiment.
Mylar bags are always a favorite for storing freeze-dried condiments. They’re lightweight and great for limited storage space. If ever you know you’re going to a place where the cream is hard get, they fit easily in your bag or luggage. No worries about breaking and spilling the condiment.
Mason jars are also great, especially if you can’t get enough sour condiment. They’re easy to open and reseal on demand. What’s better here is that the vacuum sealers are straightforward to use, and you can seal the jars even without electricity.
Don’t forget to add oxygen absorbers as well. They absorb excess oxygen from the bag or jar space to help keep your freeze-dried condiment longer.
Usually, you need to mix 3 parts of water with 5 parts of sour cream. For easier and faster reconstituting, grind or pound your freeze-dried sour cream into a fine powder. Then slowly add cool or tepid water until you get the consistency of cream at room temperature.
But what if you want the fresh, creamy texture? After reconstituting, let the sour cream rest in the fridge for 30 minutes to an hour. Then, when it’s cool enough, whip it up until you get the creamy consistency the cream is famous for.
Freeze-drying experts aren’t confident about the shelf life of freeze-dried condiment. It’s because 105 grams of sour cream contains 2.5g of fat. Fat doesn’t freeze dry well, so the cream may not be dry enough to stand decades of storage. But under ideal storage conditions, it may last for 5-10 years.
