Making Infused Oils
Turning a plain bottle of oil into a concentrated flavor base is the simplest way to upgrade a kitchen. Once you understand the basic ratios and safety constraints, you can customize oils to match whatever is on your dinner menu.
Freshness determines the shelf life
Use only thoroughly dried herbs or fully dehydrated aromatics to prevent moisture from entering the oil, which is the primary cause of spoilage. Always store your finished oils in the refrigerator and use them within a week.
- Heavy-bottomed saucepan
- Fine-mesh strainer
- Sterilized glass bottle
- Cheesecloth
What goes in.
- 1 cupNeutral oil (grapeseed, canola, or light olive oil)
- 1/4 cupHard aromatics (crushed garlic, dried chiles, or peppercorns)
Keep it below a simmer
If you see bubbles forming around your aromatics, the heat is too high. You want the oil to feel warm to the touch, not bubbling, to prevent the aromatics from frying and turning bitter.
The method.
Prepare the aromatics
Ensure all herbs or spices are completely dry. If using garlic or ginger, smash them lightly to expose the oils.
Warm the oil
Place the oil and your chosen aromatics in a small saucepan over the lowest heat setting your stove allows.
Infuse
Hold the oil at a low, gentle warmth for 15 to 20 minutes. The aromatics should soften without browning or turning crisp.
Strain
Remove from heat and let it cool completely. Pour through a fine-mesh strainer lined with cheesecloth into a clean glass bottle.
Other turns to take.
Chili Oil
Use dried red pepper flakes; increase the heat slightly for a minute at the end to deepen the color, then remove immediately.
Herb Oil
Best made with woody herbs like rosemary or thyme. Remove the herbs as soon as the oil is aromatic to keep the color bright.
When it doesn't go to plan.
Discard any solids left in the oil after straining; they will turn rancid quickly.
Store in a dark cupboard or the fridge to preserve the color and flavor intensity.
If the oil clouds up in the fridge, let it sit on the counter for ten minutes to return to a clear, liquid state.
The ones that keep coming up.
Can I leave the garlic inside the oil bottle?
No. Removing the solids is essential for safety and flavor, as the aromatics will break down and spoil the oil.
