Buying, Storing, and Cooking with Spices

Buying, Storing, and Cooking with Spices


PANTRY DIVE

Take a closer look at your favorite pantry ingredients. This week, it’s all about spices. (But of course, feel free to revisit the pocket guide to vinegars.)

Cooking with a well-stocked spice cabinet is a joy. It makes your food more aromatic, vibrant, and bold with relatively minimal effort. But spices are some of the more misunderstood players in the home-cooking game. Questions we hear a lot from readers: Are more-expensive brands worth it? How long do spices last? Do they go bad? Should I be buying whole or ground? What’s the best way to cook with them?

They’re all good questions, so we did a little research (nerding out over food-science king Harold McGee). Turns out, it’s not as complicated as it seems. A few easy-to-remember tips can inspire you to shop confidently and season generously.

Start with Good Sourcing

Upgrading to high-quality spices will make a huge difference in your cooking. They’re fresher, which means they have a more vibrant color, a deeper aroma, and a more pungent flavor. They might cost a bit more than the average supermarket variety, but if stored properly, they’re a worthy investment. Even within the top-tier spice market, though, it can be hard to know just what brand to buy.

Unfortunately, there’s a lot of fraud in the global spice industry. Similar to what we’ve seen happen with olive oil, honey, and seafood, it’s usually a matter of diluting a product to increase profit. So how do you know when you’re getting the real thing? Our strategy is to be an informed consumer. Not that you have to read an entire dissertation about the global spice trade to buy a jar of paprika, but take a peek at some websites. Is the brand transparent about sourcing? Does it mention seasonality, particular growing regions, or specific farms? Does it have equitable trade practices with these producers? What about regenerative farming and ecological impact? If a brand is open about its supply chain and its global impact, that’s a green light. (See below for the brands we buy.)

Care for Your Spice Investment
with Smarter Storage

The best way to extend the life of your spices is to know its enemies. Light, heat, air, and humidity are the harbingers of staleness. Spices won’t ever go bad, per se, and it’s unlikely they’ll become unsafe to eat, but the color may start to dull, and the flavor might be a bit muted. The better the storage system, the longer you can keep those spices fresh.

Spices should be stored in airtight jars (usually the ones they come in are fine, but if you’re buying bulk in bags, you’ll want to transfer them). Bonus points if the jars are opaque or darkly colored to block out light. Store them in a cool, dark, dry part of your kitchen—away from the heat of an oven or stove top and not in a moist environment, like a refrigerator.

The Science of Cooking with Spices

If you read South Asian recipes, you’ll notice there’s often a step where whole spices are cooked in a hot fat, like oil or ghee. In many Latin American recipes, whole spices and chilies are dry-toasted in a hot pan before being ground. These methods make the flavor of your spices much more powerful.

Food scientist Harold McGee touches on this process (and pretty much any other food question you could possibly have) in his acclaimed book On Food and Cooking. “Herbs and spices stockpile their aroma chemicals in specialized oil-storage cells,” he writes. “[They’re] in glands on the surfaces of leaves, or in channels that open up between cells.” In the wild, these essential oils—the same ones we covet for flavor and aroma—function as the plant’s defense mechanism.

As a cook, your goal is to coax those aroma chemicals out of the herbs and spices. There are a few ways to do this.

  1. Add heat

    The hotter these aroma molecules get, the more easily they’ll release flavor.

  2. Break them down

    Think of a bartender muddling herbs or twisting lemon peel to release the essential oils. Ground, crushed, and chopped herbs and spices are more flavorful for a couple of reasons. First, all of those actions will cause friction, which generates heat, and heat equals flavor. Second, by breaking down these ingredients, you’re creating surface areas for those aroma molecules to escape from and get into your food.

  3. Use fat

    Since they’re oils, aroma chemicals are fat-soluble. If you add them to a warm fat like oil, butter, ghee, or animal fat, they’re able to release a ton of flavor. Also worth noting: Because fats have a palate-coating effect, a fat infused with spice will have a full and intense taste.

To Grind or Not to Grind

We like to have a mix of whole and ground spices. There’s nothing wrong with buying preground spices. It’s convenient, and if you’re purchasing high-quality product and storing it properly, it should remain fresh for a while. But because ground spices tend to lose their flavor sooner than whole spices, we opt for ground versions of the spices we use most frequently and whole versions of the spices we might need to store for longer.

If you want to grind your own whole spices, give them a quick toast in a dry pan, then crush in a mortar and pestle or blitz in a coffee grinder. Be sure to have a dedicated coffee grinder for spices…unless you want cumin in your next latte.

There are so many different ways to incorporate whole or ground spices into your repertoire, but if you’re wondering which one is best suited to your recipes, think about it this way: Based on McGee’s assessment of how grinding, crushing, and chopping affects flavor, we know that ground spices have greater surface area from which to release flavor. That means they’ll become aromatic more quickly. So if you need max flavor with a short cook time—like spiced nuts, cauliflower chorizo tacos, or spiced carrot soup—ground is the way to go.

Whole spices—while potent—will release their flavor more gradually and are better-suited for longer cook times or slow steeping, which allows them to deeply infuse whatever they’re in. We like to use them for mulled cider or wine, in a fragrant lamb tagine, or to round out brines for homemade pickles.

Social responsibility is an important part of Burlap & Barrel’s brand identity. For founders Ethan Frisch and Ori Zohar, transparency, equitable trade, and sustainability are the big priorities. By working directly with farmers, they’re able to source spices that are a much higher quality than what you’d get at a supermarket. Burlap & Barrel has all the essentials, but look out for its more unusual offerings like ground black lime, Turkish oregano buds, and wild Icelandic kelp.
