Have you ever wondered how astronauts enjoy ice cream in space? The answer lies in freeze-dried ice cream, also known as мороженое для космонавтов или space ice cream. This unique treat was first developed by NASA for the Apollo missions in the 1960s and 1970s, and it has since become a popular novelty item found in science museums and gift shops. But did you know you can make your own freeze-dried ice cream at home? In this guide, we’ll walk you through everything you need to know about making мороженое для космонавтов, from the basics of freeze-drying to storage tips and even alternative methods if you don’t have a freeze dryer. Let’s dive in!
What is Astronaut Ice Cream?
Astronaut ice cream is a freeze-dried version of regular ice cream. The process removes all the moisture, leaving behind a lightweight, crunchy treat that doesn’t melt. It’s shelf-stable, making it perfect for long-term storage—up to 25 years when properly stored! The texture is airy and porous, similar to a crunchy wafer, and it melts in your mouth as you eat it. Often referred to as space ice cream, this treat is not only fun to eat but also a great way to preserve your favorite flavors.
How to Make Freeze-Dried Ice Cream
Step 1: Preparing the Ice Cream
Before you start the freeze-drying process, you’ll need to prepare your ice cream. Here’s how:
- Choose Your Flavor: You can use store-bought or homemade ice cream. Popular flavors include vanilla, chocolate, and strawberry, but feel free to get creative!
- Shape the Ice Cream: Use a cookie scoop to create individual ice cream balls, or spread softened ice cream in a thin layer on a tray. If you’re spreading it, score the ice cream into individual servings for easier storage later.
- Pre-Freeze: Place the ice cream in a deep freezer for at least 2 hours (up to 24 hours for best results). This step ensures the ice cream is solid before freeze-drying.
Step 2: Using a Freeze Dryer
If you have a freeze dryer (like the popular Harvest Right freeze dryer), follow these steps:
- Load the Trays: Place the pre-frozen ice cream on the trays. If desired, line the trays with parchment paper for easier removal.
- Set the Machine: Select the appropriate settings on your freeze dryer. For ice cream, choose Liquid > Frozen and set the pre-freeze time to 30 minutes.
- Start the Process: The freeze dryer will first freeze the ice cream to around -41°F (-40°C), then use a vacuum pump to remove moisture through sublimation. This process can take 24 hours or more, depending on the thickness of the ice cream.
- Check for Dryness: Once the cycle is complete, test the ice cream by breaking a piece in half. It should be lightweight, dry, and have a styrofoam-like texture. If there’s any moisture, add more drying time.
Storing Freeze-Dried Ice Cream
One of the best things about мороженое для космонавтов is its long shelf life. Here’s how to store it properly:
- Airtight Containers: Use Mason jars with a vacuum sealer or Mylar bags with oxygen absorbers to keep the ice cream fresh.
- Room Temperature: Store the containers in a cool, dark place. Freeze-dried ice cream can last up to 25 years without refrigeration!
- Labeling: Always label your containers with the date and flavor to keep track of your stash.
The Unique Texture and Taste of Astronaut Ice Cream
Freeze-dried ice cream is crunchy and dry to the touch, but it melts in your mouth, releasing its full flavor. The higher the quality of the ice cream you start with, the better the end result. It’s a fun, novel treat that’s perfect for snacking or as a conversation starter! Often called space ice cream, this treat is a favorite among both kids and adults.
Alternative Method: No Freeze Dryer? No Problem!
Don’t have a freeze dryer? You can still make a similar treat using your oven. Here’s how to make fake astronaut ice cream with meringue:
Ingredients:
- 4 large egg whites
- ¼ teaspoon cream of tartar
- 1 cup sugar
- 1 tablespoon vanilla extract (or other flavoring)
- Gel food coloring (optional)
Instructions:
- Preheat the Oven: Set your oven to 200°F (93°C) and line a baking sheet with parchment paper.
- Make the Meringue: Whip the egg whites and cream of tartar until frothy. Gradually add the sugar and vanilla, continuing to beat until stiff peaks form.
- Shape the Meringue: Use a cookie scoop to create small mounds of meringue on the baking sheet, resembling ice cream scoops.
- Bake: Place the meringue in the oven and bake for 2-3 hours, or until the meringue is dry and airy. Avoid browning.
- Cool and Serve: Let the meringue cool completely before serving. Store any leftovers in an airtight container for up to 3 weeks.
Rehydrating Freeze-Dried Ice Cream
While freeze-dried ice cream is typically eaten as-is, you can rehydrate it for certain recipes or experiments. Simply add water gradually until the desired consistency is reached. For precise rehydration, weigh the ice cream before and after freeze-drying, and add back the exact amount of water removed.
Tips for Freeze-Drying Different Ice Cream Flavors
Not all ice cream flavors freeze-dry the same way. Here are some tips:
- Fruit or Nut Add-Ins: Ice cream with chunks of fruit or nuts may require longer freeze-drying times.
- Шоколад: Chocolate coatings or swirls can be tricky, as the sugar and fat may not freeze-dry well. Experiment with small batches to find the right settings.
- Creamy vs. Icy: Creamier ice creams tend to freeze-dry better than icy ones, as they have a more uniform texture.
