Here are some tips to preserve garlic and onions for an entire year without mold or spoilage

Store in the refrigerator

Storing whole garlic and onions in the refrigerator can be effective for keeping them fresh for a long time. If you want to save time and effort, you can peel the garlic or onions in advance and place them in an airtight jar or container before refrigerating. You can also mince the garlic, divide it into portions, and store it in the fridge. This method not only saves time but also helps retain the flavor and quality of the garlic for an extended period.

Store onions in mesh bags, paper bags, or baskets

Proper ventilation is crucial to keep onions dry and fresh. Do not use plastic bags or sealed containers, as they block airflow and cause onions to rot or grow mold more quickly.

Place the onion basket or bag in a cool, well-ventilated spot in your kitchen. Avoid areas with very low temperatures (below 10°C) or high heat. Regularly check the onions and remove any that are soft, discolored, or starting to rot to prevent mold from spreading to the others.

Whole onions are not difficult to store. For fresh, unpeeled onions, you don't need to refrigerate or freeze them—simply keep them in a cool and airy place in your kitchen.

There are many ways to store garlic and onions

Using tea leaves, salt, and baking soda

Another simple and effective way to preserve garlic is with a mixture of green tea, baking soda, and salt. This combination helps absorb moisture and keeps the garlic dry. Additionally, tea and salt have antibacterial properties that prevent sprouting and spoilage.

First, after purchasing garlic, dry it under the sun for about 1 hour or leave it in a dry, airy place for 1–2 days to remove moisture from the outer skin.

Next, place the garlic in a plastic bag. Mix about 40–50 grams of salt, baking soda, and green tea, wrap the mixture in a paper towel, and place it into the bag with the garlic. Use your hands or a vacuum sealer to remove as much air as possible and tie the bag tightly. Store the bag in a cool, dry place away from direct sunlight.

With this method, garlic can be preserved for up to a year without sprouting or going bad.

Proper freezing method for garlic

Peel and mince the garlic, then place it into an airtight bag. Spread it flat into a thin layer and freeze it for about 3 hours. Then take it out and cut into small squares. You can also press minced garlic into an ice cube tray, wrap it tightly, and place it in the freezer.

Preserving garlic in oil

Peel the garlic cloves and place them into a glass jar or food container. Pour oil over the garlic until fully submerged, seal the lid tightly, and store it in the refrigerator or freezer. When needed, simply scoop out the garlic with a spoon.

Long-lasting and worry-free

Using baking soda and ginger

Just prepare 2 tablespoons of baking soda and one piece of ginger. Place both in a ziplock bag and press out all the air before sealing. Baking soda absorbs moisture while ginger has antibacterial properties, helping the garlic stay fresh longer.

For the best results, store the bag in a cool, ventilated area away from direct sunlight. This combination of baking soda and ginger helps keep garlic fresh, flavorful, and safe for extended periods.

Dehydrating garlic

Dehydrating garlic is another effective preservation method. When garlic is dried, it loses moisture, becomes more compact, and easier to store. Additionally, dried garlic rehydrates during cooking, releasing a rich flavor that enhances dishes.
