Yellow Mustard

Published August 2010

How we tested

Smooth and mild, yellow mustard is a North American thing. In other parts of the world, mustards are hotter, darker, and grainier. But what yellow mustard may lack in worldliness and guts, it makes up for in versatility. Yellow mustard is as much at home on a ballpark hot dog as it is on cold cuts or in potato salad, barbecue sauce, salad dressing, or marinades for chicken or pork. To determine which yellow mustard is best, we bought seven nationally available brands and called 24 cooks and editors from America’s Test Kitchen to taste them plain and with steamed hot dogs.

Yellow mustard is made from white (also called yellow) mustard seed, which is flavorful but doesn’t cause any of the nasal burn of brown or black mustard seed; these last two are used in Dijon, Chinese, and other spicy mustards. Our tasters wanted to actually taste the mustard seed; the two brands they judged to have the most mustard flavor both list mustard seed second in their ingredients. The other brands list it third (meaning there is proportionally less of it). The amount of salt also proved key. We often prefer saltier foods in our tastings, but this time the mustards with the least sodium tended to score higher. Why the break in preference? Vinegar adds so much pungency, these yellow mustards didn’t need extra seasoning; indeed, too much salt threw the flavors out of balance.

Two top-selling, familiar mustards scored well, as we’d expect, but surprisingly they were edged out of the winner’s circle by a small organic brand which tied for having the least sodium. Tasters appreciated the heat and tang of our winner as well as its relatively complex but well-balanced flavor.

And here’s something else to keep in mind when you’re shopping: The molecule that gives yellow mustard its assertive taste (4-hydroxybenzyl isothiocyanate, or PHBIT) dissipates over time, so note the freshness date on the jar.

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."
