Cold Infusion Basics for Herb Oils

Want to make flavorful herb-infused oils without heat? Cold infusion is the way to go. It preserves the delicate flavors of herbs while maintaining the oil’s natural properties. Here’s a quick overview to get started:

• Use dried herbs like rosemary, thyme, or oregano to avoid moisture and prevent bacterial growth.
• Choose high-quality extra virgin olive oil (EVOO) with a crush date within the last 9 months for the best results.
• Patience is key: Infuse for 2–6 weeks in a cool, dark place for maximum flavor.
• Safety matters: Keep tools clean, herbs dry, and oils stored properly to prevent mold or botulism.

Choosing Ingredients

Herb Selection

Picking the right herbs is key to crafting a successful cold infusion. Dried herbs are usually the better choice over fresh ones because they contain less moisture, which helps minimize the chance of bacterial growth. When selecting your herbs, go for ones that are dry and crisp, vibrant in color, and free from musty or unpleasant smells. Properly stored herbs - kept in airtight containers away from sunlight - are ideal.

Some of the most popular dried herbs for oil infusion include rosemary, thyme, oregano, and sage. These Mediterranean herbs pair beautifully with extra virgin olive oil. For the best flavor, aim to use your dried herbs within six months of purchase. Once you've picked your herbs, the next step is choosing a high-quality oil to complement and enhance their aromas.

Oil Selection

A great herb-infused oil starts with a premium base oil. When selecting your oil, pay attention to these key qualities:

• A fresh crush date within the last 9 months
• A clear, bright appearance with no cloudiness
• A clean, fruity aroma free from any rancid notes

For example, Big Horn Olive Oil's Estate Reserve Ultra Premium EVOO is an excellent option. It comes from the top 5% of harvests and meets all these criteria, making it a fantastic foundation for infusions. To maintain the oil's peak flavor, buy only what you can use within a few months of opening. Store any leftovers in a cool, dark spot to keep them fresh and preserve their beneficial properties.

Once you've chosen your oil, you're ready to move on to preparing the herbs for infusion.

Making Cold-Infused Oils

Herb Preparation

Start with dried herbs - either store-bought or ones you've dried yourself. If you're drying your own, make sure they are completely free of moisture by following these steps:

• Spread the herbs in a single layer on a clean, dry surface.
• Place them in a well-ventilated area, away from direct sunlight.
• Let them dry for 1–2 weeks, or until they crumble easily when touched.

Mixing Process

Cleanliness and the right proportions are key. Begin by sanitizing a glass container - clear or amber glass works great. Use the following ratio for your mixture:

Here’s how to mix:

1. Add the dried herbs to your sanitized glass container.
2. Make sure the oil is at room temperature (68°F–72°F). A high-quality extra virgin olive oil, like Big Horn Olive Oil's Ultra Premium EVOO, is ideal.
3. Pour the oil over the herbs, ensuring they are fully submerged.
4. Seal the container tightly with an airtight lid and label it with the date and contents.

Once sealed, the mixture is ready to infuse.

Infusion Time

Store the container in a cool, dark place, away from heat sources. Allow the oil to infuse until it reaches the flavor intensity you prefer. When ready, strain the oil through a fine-mesh strainer lined with cheesecloth to remove the herb particles.

Problem-Solving Guide

Mold Prevention

Keeping mold at bay is essential for successful cold infusions. The biggest culprits behind contamination are moisture, unclean tools, and improper storage. Here’s how you can prevent mold from ruining your efforts:

Preparing Herbs the Right Way

• Make sure your herbs are completely dried to eliminate moisture.
• Use a dehydrator set to 95–115°F, or air-dry your herbs in a well-ventilated space for 1–2 weeks.
• Steer clear of drying herbs on humid days to avoid trapping moisture.

Sterilizing Equipment
Cleanliness is key. Wash and dry your glass jars and utensils thoroughly before use. For extra sterilization, try one of these methods:

Once your tools are spotless and your herbs are properly prepared, you’re ready to dive into crafting the perfect infusion.

Flavor Adjustment

Once you’ve tackled mold prevention, it’s time to fine-tune the flavor of your infusion. This can be done by tweaking the herb-to-oil ratios and adjusting infusion times.

Herb-to-Oil Ratios

Timing Adjustments

• For a standard infusion, let it sit for 2–3 weeks.
• To get maximum flavor, extend the infusion time to 4–6 weeks.
• Want to go the extra mile? Try a double infusion. Strain the oil, add fresh herbs, and let it infuse for another 2–4 weeks.

Temperature Matters
Maintain a steady temperature between 65–75°F. Avoid storing your infusion near windowsills, heating vents, or any place with temperature swings.

If you notice any cloudiness, strain the oil through cheesecloth immediately. Discard any batch that shows signs of mold, unusual colors, odd smells, or bubbling.

Cooking Methods

Once you’ve chosen your herb and oil pairing, the way you use it can make all the difference. Here are some tips to preserve the flavors and integrity of your infused oils.

Low-Heat Applications

Infused oils are best used with gentle heat to avoid overpowering or altering their flavor. Try them for:

• Slow-roasting vegetables at low temperatures
• Lightly sautéing tender greens
• Finishing proteins in the pan after they’re cooked

No-Heat Uses

For maximum flavor and aroma, drizzle herb-infused oils over dishes just before serving. It’s a simple way to make any meal feel special.

Marinade Magic

Infused oils are a great base for marinades. Combine them with an acid and seasonings to create layers of flavor. Use this easy ratio:

For marinating times:

• Chicken: 2–4 hours in the refrigerator
• Beef: 4–6 hours
• Fish: Only 30 minutes to avoid breaking down the protein

Bread Service

Infused oils can even transform bread service into a standout appetizer. Serve them at room temperature (68–72°F) in small dipping bowls. With Big Horn Olive Oil products, even a simple slice of crusty bread becomes a gourmet treat.

Safety and Storage

Botulism Prevention

To reduce the risk of botulism, it's important to use oil within 9 months of its crush date. Sticking to clear guidelines for usage not only ensures safety but also helps preserve the oil's quality.

Proper storage also plays a key role in keeping your oil safe and maintaining its flavor and freshness.

Storage Methods

Storing your infused oils correctly is crucial for preserving their quality and safety. For unopened oils, follow the 9-month usage recommendation. Once opened, choose a container size that fits your consumption needs, ideally finishing the oil within a few months for the best results.
