Preserving food has been a time-honored practice that dates back to ancient civilizations.
In times when refrigeration and advanced storage techniques were not available, our ancestors relied on various methods to ensure their food lasted longer, reducing waste and ensuring a steady food supply throughout the year.
Even in the modern world, food preservation remains a valuable skill, enabling us to save money, reduce our ecological footprint, and savor the flavors of seasonal produce year-round.
While there are various modern preservation techniques, many pantry items can be used to achieve the same goal, keeping our food fresh and delicious for extended periods.
Food preservation is essential for extending the shelf life of perishable items and reducing food waste.
While many items can be used for food preservation, some commonly used options are listed below.
Among the oldest and most effective preservation agents, salt helps draw out moisture from foods, inhibiting the growth of bacteria and preventing spoilage. It is widely used for curing meats, preserving fish, and pickling vegetables.
Often referred to as salting, this is one way to preserve foods for an extended period. Salting, like many preserving techniques, changes the flavor. Thus, you will want to rinse salt-preserved foods well before eating.
While you can use salt to preserve almost anything, salted fish is one of my favorite salt-preserving recipes.
To create salted fish, rinse the fish and pat it dry. Cover the fish with a layer of salt, at least ½ inch thick. You can create layers of fish and salt if you ensure the fish is all covered in a layer of salt at least ½ inch thick.
Place the salted fish into the fridge or cold cellar for 2 days.
If you don’t have a root cellar, here’s a cheap and easy way to build a root cellar in your backyard.
After 2 days, remove the fish and shake off the excess salt. Wrap the fish in cheesecloth and place it on a rack over a plate to catch any juices. Let the wrapped fish sit in the fridge or cellar for a week.
After the week has passed, remove the cheesecloth and store the fish in a sealed container in a cool spot such as the fridge or cellar.
When you want to eat the fish, soak it in water for 24 hours before cooking, changing the water throughout to remove excessive salt.
This staple is more than a sweet treat; it also serves as a vital preservative.
When combined with fruits, sugar helps create delicious jams, jellies, and preserves, extending the shelf life of a product such as fruit that would otherwise spoil quickly.
Sugar has been used extensively to preserve fruits such as apples, pears, and berries. When sugar is added to food, it binds to the water and reduces the amount, hindering the growth of bacteria.
Although sugar is used in many ways, it is commonly turned into a syrup.
This method is called sugaring, and it is popular because it does not require the use of specialized canning equipment.
An 18th-century recipe for sugaring includes using an equal amount of sugar and fruit.
Mix the sugar (e.g., 2 cups) with ½ cup of water and cook until it fully dissolves and forms a thin syrup. Add fruit to the liquid and let it boil gently for a few minutes or until the fruit is cooked through but not mushy.
Remove the fruit from the liquid and cool both separately. Once cool, add both to a single jar. Seal and store in a cool, dark place.
With its acidic properties, vinegar is an excellent preservative, particularly in pickling. Submerging vegetables and fruits in vinegar solutions inhibits the growth of microorganisms and preserves their texture and taste.
Vinegar pickling is a popular ‘quick pickling’ process. Vinegar has a long history in food preservation and dates back to the ancient Egyptians.
When you preserve vegetables with vinegar, it means that the veggies last a long time. This is important because, generally, fresh produce will spoil quickly.
Quick pickling is super easy to do.
Start by washing and sanitizing the jars and lids and cutting up the veggies you want to preserve. Add herbs and spices to the jars. Garlic, thyme, and rosemary are all great options, but endless possibilities exist. Next, tightly pack your vegetables into the jars.
In a saucepan, combine 1 cup of white vinegar, 1 cup of water, 1 tbsp. kosher salt, and 1 tbsp. sugar. Dissolve the mixture by boiling over high heat to create a syrup.
Pour the syrup over the vegetables in the jars, leaving a ½ inch headroom. Seal and store.
Immersing food items in oil creates a barrier that helps prevent spoilage by reducing exposure to air.
This technique is commonly used for preserving herbs, garlic, or other flavorful additions. However, olive oil can also be used to protect vegetables.
Olive Oil Marinade
Marinating vegetables in olive oil is simple and so tasty. This process allows you to enjoy the summer’s bounty throughout the colder months.
You can easily store any veggie using herbs and olive oil.
Peppers, zucchini, beets, or green beans are popular options.
Whatever you choose, the vegetables used in this storage method must be fully cooked and stored in a cool, dark place.
It is also vital to ensure that the olive oil completely covers the vegetables to prevent bacteria growth.
To preserve veggies in olive oil, gather 4 cups of the vegetable to want to store and cook them thoroughly, leaving them slightly crispy.
Use 2 parts olive oil and 1 part vinegar. Season your veggies any way you like. Use garlic, salt, chili peppers, etc.
Generously coat the vegetables in ¼ cup of vinegar and let it sit for 15 minutes. Add ½ cup of olive oil. You can use more or less, but remember to stick to the 2-to-1 scale.
Place the cooked, seasoned veggies into a jar or container and add more of the mixture.
Essential for canning and pickling, citric acid heightens acidity, which is unfavorable for bacteria and molds, prolonging the shelf life of preserved foods.
Often, recipes call for using lemon juice, but citric acid shines as a substitute. While you will want to research the topic, adding ½ tsp per quart or ¼ tsp per pint is common.
Preserving food using pantry items not only harkens back to our culinary roots but also empowers us with valuable skills for reducing food waste and enhancing sustainability.
These time-tested preservation techniques, passed down through generations, allow us to enjoy the bounty of seasonal produce year-round while minimizing our environmental impact.
From the simplicity of salt and sugar to the tang of vinegar and the natural goodness of honey, these pantry items offer many possibilities to keep our food fresh, flavorful, and ready to savor.
Remember to follow proper food safety guidelines and procedures when using these pantry items for food preservation. Always sanitize jars and containers, and use fresh, high-quality ingredients for the best results.
