As summer days stretch out before us, the abundance of sun-ripened fruits and vegetables gives us an opportunity to capture the season’s bounty and extend its flavors into the colder months. Traditional preserving techniques can be a labor of love with a steep learning curve, but did you know that your sous vide machine can make this task easier and more precise? That’s right, the sous vide method isn’t just for perfectly cooked steaks and creamy custards – you can also use it for creating delectable and shelf-stable summer preserves.
When we talk about sous vide, we’re referring to a cooking method where food is vacuum-sealed in a bag and cooked to a precise temperature in a water bath. The sous vide process lends itself exceptionally well to preserving. The vacuum-sealing process inherently lends itself to preserving, and the precision temperature control allows for consistent and safe results.
Let’s take a look at how you can use sous vide techniques to make your own preserves this summer.
Preparation
The first step in making sous vide preserves is similar to traditional methods. Clean your fruit and prepare it as you normally would for a jam, jelly, or preserve. This typically involves cutting the fruit into pieces and removing any seeds or pits. If you prefer a smoother consistency, puree the fruit in a blender or food processor.
Next, you’ll need to sweeten your fruit. The amount of sugar you add will depend on the sweetness of your fruit and your personal taste. As a general rule, start with a ratio of about 1:4 of sugar to fruit by weight.
Packaging
Once your fruit is prepared, transfer it into a vacuum-sealable bag. The vacuum sealing step is crucial to prevent bacteria and yeast growth. It’s also beneficial to vacuum seal your bags to avoid any leakage during the cooking process.
Sous Vide Cooking
Now, it’s time for the sous vide process. Set your sous vide machine to 60°C (140°F). This is an ideal temperature for preserving fruit, as it’s high enough to kill common forms of bacteria and yeast, yet low enough to maintain the fresh flavor and vibrant color of your fruit.
Place your vacuum-sealed bag of fruit in the sous vide water bath and cook for 2 to 3 hours. The precise temperature control and gentle heating of the sous vide method help preserve the fresh flavor of the fruit and achieve a perfect texture in your preserves.
Preservation
After cooking, carefully remove the bag from the water bath and let it cool at room temperature. Once cool, you can store your sous vide preserves in the refrigerator, where they’ll stay fresh for up to two weeks. If you want to store your preserves longer, you can use traditional canning methods. Pour the sous vide preserves into a sterilized jar, seal it with a two-piece lid, and process it in a boiling water bath for 10 minutes.
Whether you’re a sous vide enthusiast or a preserving pro looking for a new technique, sous vide preserving offers an easy and precise method for capturing the flavors of summer. So, dust off your sous vide machine, and let’s start preserving the bounty of the season!
