Salted Butter

Published October 2014

How we tested

Though we prefer unsalted butter for most recipes because it allows finer control over flavor and texture, most of the butter sold in the United States is salted. We use salted butter as a condiment for foods like corn on the cob, biscuits, or toast when we want extra-salty, savory flavor. Since most of the times we use salted butter are when butter flavor needs to be front and center, we wondered: Is it worth shelling out more for “premium” salted butter?

To find out, we selected six nationally available products and one top-selling regional product (which is available in only 34 states but ranks second in total national sales). We asked 21 America’s Test Kitchen staffers to sample the butters plain, spread on crackers, and melted over toast.

We tallied the scores and found that we liked all the butters we tried, but it was clear that some products were in a league of their own. What set the best butters apart? Since all the products in our lineup have simple ingredient lists of just cream and salt, we looked first into the most obvious variable: salt content. But that yielded no answers—tasters scored products with comparable levels of salt vastly differently.

As we examined nutritional labels, we noticed a handful of lower-ranked products with a shield on their box indicating a “Grade AA” rating by the U.S. Department of Agriculture (USDA). Curious why this label was absent from our favorite butters, we contacted Robert Bradley, professor emeritus of food science at the University of Wisconsin. It’s often rumored that salted butter is made from lower-quality cream than is unsalted butter, but Bradley quickly dismissed that suggestion and said that the USDA doesn’t require manufacturers to grade their butter (or the cream used to make it), and a rating doesn’t necessarily guarantee a better butter. “There’s a lot better cream today going into butter manufacturing than we’ve ever had,” he said. “Handling and storage conditions have greater potential for off-flavor development than the quality of the cream used.”

Bradley confirmed what we learned from previous butter taste tests: Packaging has a huge impact on butter’s flavor potential. “Butter, like any other fat product, is a sponge for off-flavors,” he said. If not properly protected, butter quickly absorbs odors from its surroundings—usually whatever else is in the fridge. The majority of butter is packaged in either foil or wax parchment, with foil offering far greater defense from funky odors. “Parchment does next to nothing in protecting the butter,” Bradley said. “Those wrappers are as porous as a summer screen on your window.”

It wasn’t surprising, then, that the butters wrapped in plain parchment landed at the bottom of our rankings. Tasters detected a number of off, “fridge-y” flavors in these butters even though they were well within their expiration dates. Parchment-wrapped butters also had a harder, cheese-like consistency that contrasted with the airy, almost whipped texture we preferred in our top butters. Because parchment offers minimal protection from moisture loss, butters wrapped this way are likely to harden.

Foil fared much better—four of our top five butters are foil-wrapped and tasters deemed them “fresh” and “clean,” with a “soft,” “rich” texture. The fifth is packaged in a special FlavorProtect wrapper that looks like plain parchment but contains a patented moisture and air barrier that acts like foil. Though it sounds like a marketing gimmick, Bradley told us that it’s actually one of the best wrappers available and remarkably effective at keeping butter fresh. Regardless of packaging, our experts recommend buying butter with an expiration date 4 to 6 months out to minimize storage-related issues.

Not all the funky flavors we noted came from the fridge, though. Tasters were mixed on the “vegetal,” “grassy,” even “barnyard-y” flavors in a few of our lower-ranked products. Most dairy cooperatives don’t require their farmers to pasture-graze their cows, though many farmers may choose to anyway. Of the brands we tried, only two cooperatives claim their butter is made entirely from the milk of cows that are grass-fed for the majority of the year. These butters were herbaceous and earthy but a little too strong for some of our tasters, who favored nuanced, milk-forward butter.

That doesn’t mean that we prefer our butter bland, though. Our favorite product had a rich, creamy texture and a unique tanginess that set it apart. That’s because our favorite is the only butter in our lineup to undergo a process called “culturing.” Tasters overwhelmingly preferred the result—a complex, rich butter with tangy, yogurt-y notes.

So are premium butters worth the price tag? In the end, we couldn’t find a bad butter in the bunch and recommended all seven products in our lineup, but one was clearly cream of the crop. As long as you’re not baking with it (flavor nuances disappear with prolonged heating), our winner is a rich, decadent butter well worth the splurge.

The Results


Skippy Peanut Butter

In a contest that hinged on texture, tasters thought this "smooth, "creamy" sample was "swell" and gave it top honors, both plain and baked into cookies. Its rave reviews even compensated for a slightly "weak" nut flavor that didn't come through as well as that of other brands in the pungent satay sauce.

Jif Natural Peanut Butter Spread

The big favorite in satay sauce, this peanut butter's "dark, roasted flavor"—helped by the addition of molasses—stood out particularly well against the other heady ingredients, and it made cookies with "nice sweet-salty balance." Plus, as the top-rated palm oil-based sample, it was "creamy," "thick," and better emulsified than other "natural" contenders.

Reese's Peanut Butter

This is what peanut butter should be like, " declared one happy taster, noting specifically this product's "good," "thick" texture and "powerful peanut flavor." In satay sauce, however, some tasters felt that heavier body made for a "pasty" end result.

Skippy Natural Peanut Butter Spread

The only other palm oil-based peanut butter to make the "recommended" cut, this contender had a "looser" texture than its winning sibling but still won fans for being "super-smooth." Tasters thought it made an especially "well-balanced," "complex" peanut sauce.

Peanut Butter & Co. No-Stir Natural Smooth Operator

Though it says "no-stir" on the label, this "stiff" palm-oil enriched peanut butter was "weeping oil" and came across as "greasy" to some tasters. However, it turned out a respectable batch of cookies—"chewy in the center, crisp and short at the edge"—and made "perfectly good" satay sauce.

Maranatha Organic No Stir Peanut Butter

On the one hand, this organic peanut butter produced cookies that were "soft and sturdy" yet "moist," with "knockout peanut flavor." On the other hand, eating it straight from the jar was nearly impossible; its "loose," "liquid-y," and "dribbly" consistency had one taster wonder if it was "peanut soup."

Not Recommended

Smart Balance All Natural Rich Roast Peanut Butter

Besides being unpalatably "tacky" and "sludgy," this "natural" peanut butter suffered from an awful "fishy" flavor with a "weird acidic aftertaste" that tasters noted in all three applications. Our best guess as to the culprit? The inclusion of flax seed oil, an unsaturated fat that's highly susceptible to rancidity.

Smucker's Natural Peanut Butter

With its only additive a negligible amount of salt, the only truly natural peanut butter in the lineup elicited comments ranging from mild dissatisfaction ("needs enhancement with salt and sugar") to outright disgust ("slithery," "chalky," "inedible"). Cookies were "dry and crumbly" with a "hockey puck" texture, and the satay sauce was "stiff," "gritty," and "gloopy."
