Store in the Summer, Enjoy in the Winter

While spices draw their essence from various plant parts like seeds and bark, herbs are exclusively harvested from the leaves, binding them to the rhythms of the seasons. Italian cooking, a tradition near and dear to my heart, resonates deeply with the use of herbs.

They bring a richness that spices cannot, accessible to anyone who wishes to wander into the wilderness or their own back garden. From the rustic Tuscan seasoned salt to the quintessential pesto and even as a garnish, herbs are the unsung heroes of Italian cuisine.

When winter’s chill encroaches, the vibrant flavors of fresh herbs don’t have to fade away. Through age-old methods of preservation, such as drying and infusing in oils or vinegars, the zest of summer herbs can be carried into the heart of winter.

It’s a practice I look forward to each year, as I gather the last of my herbs with the foresight that they will enliven my dishes even on the shortest days.

And even for those who aren’t well-versed in the ways of the soil, these methods are a godsend for prolonging the life of store-bought herbs. No longer do I resign to throwing out what I haven’t used or watch them deteriorate in the fridge. These simple preservation techniques have saved many of my meals and kept my pantry stocked.

How to Preserve Basil for the Winter

Between the two basil types I plant for Italian dishes, it’s the Neapolitan that responds best to drying. It’s more delicate than Genovese, offering a minty scent that’s less aggressive, perfect for a subtle touch in meals where basil’s essence is desired without overpowering.

I’ve found that tying bunches and hanging them in a dry place works wonders, or laying the leaves flat to let the sun naturally cure them.

When I’m flush with basil, I make pesto in batches, which I then freeze in portions to use throughout the winter months.

Preserving Chives

My experience with chives has taught me that drying does them no favors—freezing captures their flavor much more effectively.

Chive blossoms steeped in vinegar not only impart a lovely hue but also make for an aesthetically pleasing gift when I bottle them in decorative glass.

Preserving Dill

Dill’s delicate fronds, which we affectionately call dill weed, don’t take well to drying. Freezing preserves their essence far better.

I’ve also taken to soaking the seeds in vinegar to create a dill-flavored concoction that’s a perfect complement to pickles.

Preserving Fennel

Fennel may be known for its bulb, but in my kitchen, the fronds are treasured just as much.

Freezing them is the best way I’ve found to keep their anise-like flavor profile intact, ready to be added to dishes that call for a whisper of licorice.

Preserving Marjoram

Of the marjoram that grows in my garden, sweet marjoram is the one I use most often. Drying it by tying it in bunches or spreading it under the sun preserves its flavor.

Once dry, the leaves crumble off the stem with ease, ready to be sealed away until needed.

Preserving Mint

Mint is one herb that I always use fresh, but when winter looms, I opt to freeze it to maintain that burst of cool flavor that only fresh mint leaves can provide.

Preserving Oregano

Though dried oregano doesn’t quite match the sweetness of its fresh counterpart, it’s an essential element in my Italian dishes.

Spreading the leaves to dry out in the warmth of the sun or a low-temp oven does the trick, and they’re then jarred for use in the cooler months.

Preserving Parsley

Whether it’s curly or the flat-leaf Italian variety, parsley dries well, though it only somewhat resembles its original taste.

I either dry it quickly in the oven or choose to freeze it for that fresh flavor when needed.

Preserving Rosemary

Rosemary can be a bit less potent when dried, but it still retains its distinct flavor. I either hang the sprigs to air dry or strip the dried leaves off their woody stems, making sure to store only the needles to avoid a tough texture.

Chopping them finely before use distributes their flavor more evenly. For recipes that benefit from the fuller flavor of fresh rosemary, I’ve found that freezing the sprigs is also effective.

Preserving Sage

Sage, which is quite common in Italian recipes, intensifies in flavor when dried.

After hanging the bunches in a dry area, I gently strip the leaves and store them, being mindful that a little goes a long way with this potent herb.

Sage also finds a secondary purpose in my home: a natural deterrent for moths in my storage spaces.

Preserving Tarragon

Tarragon, often used in its dried form in Italian cooking, is potent and should be used sparingly.

Besides drying, tarragon infuses beautifully into vinegar, and I use just a few leaves to create a flavored vinegar that enhances salads, fish, and poultry dishes with ease.

Freezing tarragon is also an option for retaining its delicate leaves.

Preserving Thyme

Thyme is one of those herbs that becomes more aromatic upon drying. Removing the leaves from the stalks and allowing them to dry in a warm, dry spot concentrates their flavor.

Once dried, I store the leaves whole or crush them for a more potent kick. They’re also amenable to freezing for later use.

Freezing and Using Frozen Herbs

Freezing herbs is a straightforward task that starts with thoroughly washing and drying your herbs. Once you’ve plucked the leaves from their stems, you can choose from the following methods:

Freezing:

1. Lay the leaves on a baking sheet and freeze them briefly, just until firm. Then transfer them to freezer bags, making sure to eliminate any excess air before sealing.
2. Chop the herbs finely and pack them directly into freezer bags, again pressing out the air before sealing.
3. For another approach, chop the leaves finely and spoon them into ice cube tray compartments, adding water and then freezing.

Using Frozen Herbs:

1. With the first approach, simply take out what you need and let the herbs thaw momentarily at room temperature before chopping or adding them to your dish.
2. If you’ve gone with the second option, these can be tossed straight into warm dishes as is, or allowed to thaw for cold preparations.
3. Lastly, the herb ice cubes can be dropped into soups and sauces for an easy flavor infusion—like enhancing a simple pot of string beans with tomatoes and garlic. For those who enjoy experimenting, mix your favorite herbs in the ice trays for ready-made seasoning cubes.

Stashing herbs in this manner ensures that I can effortlessly invigorate my dishes, imparting just the right touch to a winter’s meal.

Herb-Infused Vinegars for Winter

Infusing vinegars with herbs is a creative process that brings a new dimension to my Italian cooking, especially when fresh herbs are out of season. Here’s how I typically go about it:

How to Create Herb Vinegars:

Infusing vinegars with herbs is a creative process that brings a new dimension to my cooking, especially when fresh herbs are out of season. Here’s how I typically go about it:

1. Choose your vinegar: White wine, red wine, or apple cider vinegars make excellent bases.
2. Select your herbs: Almost any herb can be used, but I’ve found that rosemary, thyme, and tarragon lend themselves particularly well to infusions.
3. Prepare the herbs: Wash and thoroughly dry your chosen herbs before gently bruising the leaves to release their essential oils.
4. Combine and steep: Place the prepared herbs in a clean bottle or jar, pour in the vinegar, and seal tightly. I let mine sit in a cool, dark place for 2 to 4 weeks, shaking it occasionally.
5. Strain and store: After the infusion period, I strain out the herbs and transfer the vinegar to a clean bottle. It’s then ready to be used to brighten up salads, marinades, or any dish needing a zesty lift.

Using Herb-Infused Vinegars:

Incorporating these vinegars into my cooking is always an exciting part of meal prep. A splash of herb-infused vinegar can instantly elevate the flavors of a dish, cutting through richness or adding a complex tang. Here’s how I use them:

1. Dressings: A simple vinaigrette made with herb-infused vinegar can transform a green salad or drizzled over roasted vegetables.
2. Marinades: For meats or tofu, the infused vinegar tenderizes and imparts depth of flavor.
3. Finishing touch: A few drops can finish a sauce or stew, adding a bright note just before serving.

Making and using herb-infused vinegars not only serves as an outlet for culinary creativity but also ensures that the vibrant flavors of my garden have a place at the table, even in the depths of winter.

Storing and Labeling Preserved Herbs

Optimal Storage Solutions

Proper storage is key to maintaining the flavor and freshness of preserved herbs. For dried herbs, an airtight container is essential. I prefer glass jars with tight-sealing lids; they prevent moisture from seeping in and diminishing the herbs’ quality.

These jars should be kept in a cool, dark place like a pantry or cupboard, away from heat sources like the stove or sunlight, as these can lead to loss of flavor and color.

When it comes to freezing Italian herbs, I’ve found that heavy-duty freezer bags or airtight containers are best. They not only prevent freezer burn but also make it easy to stack and organize in the freezer.

If you’re using the ice cube method for your herbs, once the cubes are frozen solid, pop them out and transfer them into a freezer bag to save space and use the trays for other needs.

Labeling Advice

Labeling is crucial when it comes to identifying and tracking your preserved herbs. Here’s what I always make sure to note on my labels:

1. Name of the Herb: Sounds simple, but when you’re dealing with a variety of green leaves, it’s easy to mix them up.
2. Date of Preservation: Knowing when you preserved them helps track shelf-life and ensures you use older stocks first.
3. Method of Preservation: Distinguish between dried, frozen whole, chopped, or in oil/vinegar, so you know how they can be best used in cooking.
4. Quantity: If freezing in bags, note the quantity or weight, especially if you’ve packed them in recipe-specific portions.

I use permanent markers to write directly on freezer bags or adhesive labels for jars. For a more aesthetic and reusable option, I use chalkboard labels or tags tied around the neck of jars. It’s also helpful to note any special details like “best used for marinades” or “infused with garlic,” especially when you get creative with combinations.

With these storage and labeling strategies, my kitchen is not only organized but also set for a winter full of rich, herb-inspired dishes that bring back a taste of summer with every bite.
