If you’re dealing with thicker liquids, such as sauces or purees, it’s a good idea to refrigerate them briefly to firm them up. This makes them easier to handle and less likely to spill during the vacuum sealing process.
Step-by-Step Process to Vacuum Pack Liquids
Now that you’re prepared, follow this detailed process to vacuum pack your liquids successfully.
Step 1: Fill the Bags or Containers
Carefully pour your cooled liquid into the vacuum bags or containers. Be mindful of not overfilling; leaving some space at the top is vital:
For Bags:
- Leave at least 1-2 inches of space at the top, as liquids can expand when frozen.
For Containers:
- Fill the containers slightly below the rim to allow for expansion.
Step 2: Pre-Freeze (if necessary)
For certain types of liquids, pre-freezing can significantly aid the vacuum packing process. This is especially important for thicker liquids:
- For soups or sauces, pour the liquid into bags, laying them flat in the freezer until slightly solidified. This reduces the risk of liquid being sucked into the vacuum sealer.
- Once firm, vacuum seal the bags completely.
Step 3: Vacuum Seal the Bags or Containers
If you’re using bags, place the opening into the vacuum sealer, following the manufacturer’s instructions. If you’re using a vacuum container, simply attach the lid and activate the vacuum feature.
Tip:
For bags, make sure the seal is clean and free of any liquid or debris before sealing to ensure a proper vacuum.
Step 4: Store the Vacuum-Sealed Liquid
After sealing, date the packaging and store it in your fridge or freezer. Always remember that the ideal storage temperature for liquids can vary. Freezing is recommended for long-term storage, while refrigeration is suitable for short-term use.
Step 5: Thawing and Reheating
When you’re ready to use your vacuum-packed liquids:
Thaw:
– In the fridge overnight for even thawing, or use the defrost setting on your microwave for quicker results.
Reheat:
– Pour the liquid into a pot on low heat for even heating, or microwave in a microwave-safe container.
Common Mistakes to Avoid When Vacuum Packing Liquids
Even seasoned cooks may make mistakes when dealing with vacuum-sealing liquids. Here are some common pitfalls to avoid:
1. Overfilling Bags or Containers
As earlier mentioned, leaving enough space is vital. Overfilled bags can lead to spills, while overfilled containers might not seal properly.
2. Not Cooling Before Sealing
Sealing hot liquids could cause steam to build up inside the bag, weakening the seal. Always ensure your liquids are at room temperature before sealing.
3. Forgetting to Label
Failure to label your vacuum-packed liquids can lead to confusion down the line. Ensure you label each package with the contents and the date it was sealed.
