How to choose black garlic

When choosing black garlic, look for bulbs that are firm and plump, with a glossy, dark exterior that indicates proper fermentation. The cloves should be soft and slightly sticky, showcasing a sweet, tangy aroma that is characteristic of this unique ingredient.

Avoid bulbs that feel dry or have a shriveled appearance, as these may indicate age or poor quality. Additionally, steer clear of any bulbs with mold or an off-putting smell, as these can compromise the flavor and safety of your culinary creations.

How to store black garlic

To ensure your black garlic maintains its unique flavor and health benefits, store it in a cool, dry place, away from direct sunlight. Airtight containers are highly recommended to keep moisture and air at bay, which can lead to spoilage. A pantry or kitchen cupboard with a stable temperature is ideal for short-term storage.

For longer preservation, consider refrigerating black garlic, as this can extend its shelf life significantly. Make sure to keep it in a sealed container to prevent it from absorbing odors from other foods. Avoid storing black garlic in the freezer, as freezing can alter its texture and flavor, making it less enjoyable to use in your culinary creations.

✅ Extra Tip

To enhance its unique flavor, store black garlic in a cool, dark place in an airtight container, and consider using it in dressings or sauces to add a sweet, umami-rich depth to your dishes.

How long does it last?

Black garlic has a relatively long shelf life when stored correctly. Whole bulbs of black garlic can last for up to 3 months at room temperature in a cool, dry place. If stored in the refrigerator, they can last even longer, typically up to 6 months. Once the bulbs are opened, individual cloves should be kept in an airtight container in the fridge, where they can remain fresh for about 2-3 weeks. For extended storage, black garlic can be frozen, allowing it to maintain its flavor and health benefits for up to 1 year. Proper storage is essential to prevent spoilage and to preserve the unique taste and nutritional properties of black garlic.

What to do with leftovers?

Leftover black garlic can elevate your culinary creations with its unique flavor profile. Use it to enhance dressings and marinades by blending it into vinaigrettes or mixing it with olive oil for a savory dip. Its sweet, umami-rich taste makes it a perfect addition to stir-fries and roasted vegetables, adding depth to your dishes. You can also incorporate black garlic into soups and stews for a rich, complex flavor that develops as it simmers.

For a quick snack, spread black garlic on toast or mix it into hummus or spreads for a delicious twist. If you have a surplus, consider making a black garlic paste to freeze in ice cube trays, allowing you to easily add a burst of flavor to future meals. Its versatility means you can experiment with it in pasta sauces or pizza toppings, making every bite a delightful experience.
