Brown Mustard

Products awash in vinegar didn’t cut the mustard with our tasters.

How We Tested

When it comes to mustard, yellow tends to hog all the glory, zigzagging up ballpark franks and cornering the market on pretzel-stand squeeze bottles. But here at the test kitchen we like brown mustard, too, for its spicy, robust flavor. Unlike the yellow stuff, which gets its bright, mild character from white mustard seeds, brown mustard is made from the smaller, hotter brown seeds along with some of their bran, the tough outer layer of the seed that gives the mustard its speckled look. We use brown mustard to pack a punch when we’re eating rich foods like pastrami, ham, or eggy breads.

Which mustards didn’t pass muster? Our tasters expected their spicy brown mustard to be, well, spicy. We wanted to feel the burn, and in every taste test, hotter mustards scored higher. Mustard’s heat is a defense mechanism of the mustard plant against insects looking for something to chomp on; when its seeds are crushed, enzymes are freed and start to convert dormant chemicals into hot mustard oil. We measured the amount of mustard oil in each product, but surprisingly, the results didn’t line up. Some of the hotter products that we preferred had plenty of mustard oil, but so did the product that ranked lowest, which tasters called “weak” and “wimpy.” If we liked hotter mustards, why did one of our lowest-ranked products contain so much of the very compound that makes mustard hot?

A couple of the mustards boast “#1 grade mustard seed” on their ingredient lists, so we turned first to the quality of the seeds. But when we looked into it and found that all the mustards that we tested are made with top-grade seeds, whether stated or not, we realized that it was time to examine the mustard-making process. Mustard is created by mixing crushed seeds with a cold liquid (a cooler temperature is required to correctly activate the enzymes). Then an acid is added to slow the formation of mustard oil, keeping the mustard from becoming blow-your-head-off spicy. The most common acid, used by every product that we tasted, is vinegar because of its three-pronged effect of taming heat, prolonging shelf life, and adding tang. But when there’s too much vinegar, the formation of mustard oil is slowed too much, and the condiment loses its characteristic burn.

If more vinegar means less heat, we now understood why some products with lots of mustard oil fell flat and why tasters consistently rated overly tart products low in both heat and overall flavor. We measured each mustard’s acidity to get at vinegar content and found that more acidic products, usually those with more vinegar, rated lowest in our taste tests. In sum: Mustards with both a high percentage of mustard oil and a moderate amount of vinegar came out on top and were praised for being complex and multidimensional. Our tasters also demanded mustards that were smooth and creamy and adhered well to hot dogs. Mustards that were gritty, chunky, or runny got lower scores.

In the end, our winner took the top spot thanks to its bold heat, gentle tang, and smooth texture. That said, there are quite a few good brown mustards on the market, as we can recommend five of the seven that we tasted, and a sixth with some reservations. So what should you do if one of our two bottom-ranking products is lurking at the back of your fridge? Use it in a recipe. When we enlisted our products as a condiment, distinctions among them were obvious and important, but when they were put to work as a supporting ingredient, unbalanced mustards were rounded out by other flavors. So when we sampled each mustard in a batch of deviled eggs, tasters could scarcely detect differences in either flavor or texture, even when we doubled the amount of mustard called for in the recipe.

Methodology

To find the best brown mustard, 21 test kitchen editors and cooks sampled seven nationally available products in three blind taste tests: plain, in deviled eggs, and with boiled hot dogs.

Design Trifecta 360 Knife Block

Admittedly expensive, this handsome block certainly seemed to live up to its billing as “the last knife block you ever have to buy.” The heaviest model in our testing, this block was ultrastable, and its durable bamboo exterior was a breeze to clean. Well-placed medium-strength magnets made it easy to attach all our knives, and a rotating base gave us quick access to them. One tiny quibble: The blade of our 12-inch slicing knife stuck out a little
