Was it too much to ask for a blue cheese dressing that was thick, creamy, and actually tasted like blue cheese?

Nothing dresses up a wedge of iceberg or offsets the spicy heat of Buffalo wings quite like blue cheese dressing. There are dozens of supermarket options, but we narrowed the field to seven top-selling national products from a list compiled by Chicago-based market research firm IRi. (When a company made more than one version, we chose its best seller.) We sampled the dressings with celery sticks and with Buffalo wings.
What flavor did our tasters demand from blue cheese dressing? The unmistakable sharp, salty, sour, and pungent flavor of blue cheese, naturally. Some of the dressings had plenty of rich, creamy dairy flavor but barely tasted of this distinctive cheese; these dressings, we noticed, listed buttermilk ahead of blue cheese on the label, meaning that they contained more buttermilk than cheese. Blue cheese is veined with Penicillium roquefortii, a bluish-green mold that ferments over a period of months to produce methyl ketones and free fatty acids, the compounds that create typical blue cheese taste. All the dressings contained blue cheese, but our favorite had the most, listing it three times (in slightly different forms) on its ingredient list.
As for texture, the thicker the dressing the better—runny and thin isn’t for dipping. And we preferred sizable, creamy chunks of cheese to negligible flecks. What we didn’t expect was that a shelf-stable bottle would best refrigerated products, its distinct blue cheese flavor and thick texture making it the all-around favorite.
In fact, we liked most of the shelf-stable dressings, recommending all but one. It failed because it was too sweet. With 4 grams of sugar per serving, it had the highest sugar content of all the dressings in our lineup. The sugar was listed third on its ingredient list, ahead of even the blue cheese; the rest of the dressings had 1 gram of sugar or less. The other product we can’t recommend had almost no blue cheese flavor.
Since oil is listed first on the ingredient list in every one of these dressings, naturally the type of oil also affected our rankings. All the products we liked use soybean oil. The two products we didn’t like were made with canola oil. Canola is much more highly unsaturated than soybean oil and oxidizes more rapidly, potentially creating background rancid flavors in less than six months. It can turn bad especially quickly in a clear container, which is how all the dressings are packaged, even when the bottle is still sealed. Our favorite product also adds preservatives and partially hydrogenated soybean oil, which makes it even less likely to oxidize. It’s the only dressing in our lineup with nucleotides (disodium inosinate and...
