I use herbs preserved in oil the same way I use fresh herbs. They are particularly good in soups, stews, and salad dressings, where their vivid flavors can transform an ordinary dish into a spectacular one.
Herb butters are even more versatile. I use them in sandwiches, pasta, seafood, meat, poultry, popcorn—anything that tastes good with butter and herbs will benefit. I even replace plain butter with herb butter when making cakes and cookies.
Spend just an hour whizzing up a few batches of herb oils and butter, and you’ll be rewarded all winter long with vibrant flavors and delicious meals. Not to mention fond memories of your summertime herb garden.
How to Preserve Fresh Herbs in Oil or Butter
- Wash herbs, discarding stems and damaged leaves. Spin leaves dry in a salad spinner or dry well with paper towels.
- Place herbs in food processor with ⅓ cup olive oil for every 2 cups leaves, or ½ cup unsalted butter (1 stick) per 2 to 4 tablespoons leaves.
- For butters, add grated citrus rind, ginger, or garlic for extra flavor.
- To make sure herb oils are adaptable to a wide variety of uses, don’t add cheese or nuts.
- Pulse processor, scraping down sides of bowl from time to time, until you get a chunky paste and all leaves are chopped.
- To package for freezing, put 1 cup herb oil or ½ cup herb butter in a 1-quart zip-top bag, then flatten and spread mixture to make a thin layer. Freeze flat.
- Best used within 6 months.
