You've got a recipe that calls for cream of tartar, and suddenly you're staring at your kitchen cabinets wondering if you actually own this ingredient. Or maybe you're at the grocery store, wandering the spice aisle like it's a maze with no exit.
Sound familiar? You're definitely not alone.
Finding cream of tartar isn't complicated — but if you've never bought it before, it helps to know where to look. Let me save you some wandering.
Cream of tartar is one of those ingredients that sneaks into recipes when you least expect it. That said, one minute you're casually making cookies, the next you're hunting through half-empty spice jars wondering if you've ever even seen this stuff in real life. Worth adding: the good news? It's easier to find than you think. And once you know exactly where to grab it, you'll never wander that aisle again.
What Exactly Is Cream of Tartar?
Before we talk about where to find it, let's clear up what it actually is — because the name sounds a little weird, right?
Cream of tartar is potassium bitartrate, a byproduct of winemaking. Practically speaking, when grape juice ferments into wine, cream of tartar crystals form on the sides of the barrels. Those crystals get purified and ground into the fine white powder you see in stores.
It's acidic, which is why it shows up in recipes. In practice, bakers use it to stabilize egg whites, prevent sugar crystallization, and activate baking soda in recipes that don't have any acidic liquid. If you've ever made meringue that collapsed, cream of tartar might have been the missing piece.
You might also encounter it as a cleaning agent or in some homemade play dough recipes. Versatile little ingredient.
The Many Names It Goes By
Here's where people sometimes get confused. Cream of tartar goes by a few different names:
- Potassium bitartrate (the scientific name)
- Tartaric acid (not quite the same thing, but related)
- White tartar
Most stores just label it "cream of tartar" on the container, so you won't need to hunt for the scientific version. Just look for the familiar yellow or orange spice jar with that classic label.
Why Finding the Right Store Matters
So why write a whole article about where to buy cream of tartar? Because people actually struggle with this more than they should.
Maybe you're new to baking. Plus, maybe you moved to a new place and your old grocery store had it in a different spot. Maybe you've been substituting it for years and finally want to use the real thing. Whatever the reason, knowing your options means you won't give up and abandon that recipe halfway through.
There's also the matter of quality and pricing. In practice, a specialty store might charge twice as much for the same size jar. Understanding where to look means you can grab it affordably without a special trip.
Where to Buy Cream of Tartar
Here's the part you've been waiting for. Cream of tartar is sold in most places that carry baking supplies, and it's not exactly a rare item. Here's where you'll find it:
The Grocery Store
This is where most people grab it, and it's usually the easiest option.
Look in the spice aisle, often near the baking supplies. It's typically stocked with other common spices like cinnamon, nutmeg, and garlic powder. Look for it on a middle shelf, usually in a small glass or plastic jar.
The exact location varies by store:
- Kroger, Safeway, and similar chains: Spice aisle, often in the baking section nearby
- Walmart: Spice aisle near the baking supplies
- Target: Usually in the culinary aisle or with baking goods
- Whole Foods and Sprouts: With spices and baking ingredients
Most standard grocery stores carry it. The only time you might have trouble is at very small convenience stores or gas stations, which typically only stock the bare essentials.

Bulk and Discount Stores
If you use cream of tartar regularly, buying in bulk makes sense.
Costco, Sam's Club, and BJ's sometimes carry larger quantities. You won't always find it, but when you do, the price per ounce is usually better than the grocery store.
Amazon and other online retailers are solid options too, especially for bulk amounts or specialty brands. Just factor in shipping costs if you're only buying one small jar — it often ends up pricier than picking it up locally.
International and Specialty Markets
Here's something most people don't realize: cream of tartar is extremely common in Indian, Middle Eastern, and Latin American cooking too.
In Indian grocery stores, it's often sold as citric acid or listed under its Urdu/Hindi name. Check the international foods aisle or ask someone working there — they'll point you in the right direction.
Some specialty baking supply stores also carry it, usually in larger quantities meant for serious bakers or small food businesses.
Drugstores and Convenience Shops
Small quantities of cream of tartar occasionally show up at CVS, Walgreens, or Rite Aid in their personal care or baking sections. But honestly, your odds are better at an actual grocery store. These places tend to have limited baking supplies.
What to Look for When Buying
Not all cream of tartar is created equal, but for home baking purposes, the standard grocery store variety works perfectly fine.
Check the label: Make sure it says "cream of tartar" or "potassium bitartrate." You want pure powder with no added ingredients.
Size matters: Most jars are small — usually 1.5 to 3 ounces. This is fine for occasional baking. If you're making a lot of meringue or homemade play dough, consider a larger quantity.
Organic options: If you're looking for organic cream of tartar, check Whole Foods, Sprouts, or the natural foods section of larger stores. It'll cost more, but some people prefer it.
Freshness: Unlike spices that lose potency over time, cream of tartar stays good almost indefinitely. There's no real expiration concern, so don't stress about the "best by" date too much.
Common Mistakes When Shopping for Cream of Tartar
People make a few blunders when hunting for this ingredient:
Looking in the wrong aisle. It's not in the baking aisle with flour and sugar — it's usually with the spices. That threw me off the first time I bought it.
Confusing it with tartar sauce. Some people mentally link "tartar" with seafood tartar sauce. Cream of tartar is a completely different thing — it's a fine white powder, not a condiment.
Buying the wrong product. Make sure you're getting cream of tartar, not tartaric acid (which is more concentrated and used in different applications). The labels can look similar if you're not paying attention.
Assuming it's expensive. A small jar usually costs less than $3. It's not a
It’s not a luxury item that will break the bank, especially when considering how essential it is to many classic recipes. For these reasons, investing the modest expense required to acquire a reliable container is well worth it. That's why cream of tartar serves multiple functions in baking—it stabilizes meringues, helps leaven cakes, and contributes subtle acidity that balances sweetness. In fact, a quality jar typically retails for under three dollars, making it one of those pantry staples that feels like a bargain. Skipping it isn’t just a minor oversight; it can dramatically change the texture and rise of your baked goods. Even so, the true value lies beyond mere cost. Whether you’re a seasoned baker or someone who only dips into the kitchen occasionally, having easy access to this humble ingredient prevents last‑minute scrambling for substitutes.
