Supermarket Burrata

Published July 2018

How we tested

Imagine a tender ball of fresh mozzarella. Now imagine slicing it open to find a luscious, thick cream teeming with plush bits of curd. This offshoot from mozzarella is called burrata, and it's made in much the same way as mozzarella: Milk and rennet are cooked until the curds (solids) separate from the whey (liquid), and then the curds are stretched into a creamy round ball. Burrata has one additional step: Just before the ball is twisted and sealed, it's stuffed with a mixture of mozzarella curd and cream. It's a showstopper of a cheese that is often served simply with bread or cured meats and split dramatically at the table.

Unlike many Italian cheeses such as Parmigiano-Reggiano and mozzarella—both of which can trace their production back to at least the 16th century—burrata is a relatively new invention. Cheesemakers in the Puglia region of southern Italy started making it in the early 20th century as a way to use up the bits of cheese left over from production of fresh mozzarella. They traditionally wrapped the final product in the long green leaves of asphodel (Asphodelus albus), a plant native to the Mediterranean. The leaves helped indicate freshness: Green, bright leaves meant the cheese was fresh, while dry or browning leaves suggested that it was past its prime.

Burrata remained a regional delicacy scarcely found outside of Puglia until about 1950, when cheese factories began to make it on a larger scale for distribution across Italy. Then, in the late 20th century, small, artisanal cheesemakers in the United States started producing burrata; large manufacturers including BelGioioso and Calabro eventually followed suit.

We wondered if we could find a good-quality burrata at the supermarket, so we rounded up four nationally available products, priced from $3.80 to $6.50 for 8 ounces. We sampled each plain at room temperature, as burrata is meant to be served, and in our Heirloom Tomato and Burrata Salad with Pangrattato and Basil.

A Distinct Shell Plus Filling

There were clear physical differences in the burratas. Some had a hefty outer shell that held a soft center of thick, slow-oozing filling, while others seemed ready to burst at the slightest touch, immediately gushing out a wave of loose curds as soon as we sliced into the paper-thin shell. One shell was so delicate and flimsy that it practically dissolved into the filling once the burrata was sliced.

These textural differences can be created in a number of ways: Cheesemakers can adjust the amount of cream used, the amount of mozzarella, and/or the size of the curds added. Tasters favored burratas with a more substantial shell. They also preferred fillings that were thick and plush to those that were thin and milky.

We quantified the amount of shell versus filling by slicing three balls of each burrata, scooping out the filling, weighing the shell and the filling separately, and averaging the results. Our favorite products were approximately half mozzarella shell and half filling, while our lowest-ranked product was 82 percent filling and only 18 percent shell. Without a thicker shell to keep the cream contained, products with a higher percentage of filling seemed liquid-y and oozed all over our cutting board when we sliced them. We liked a tender bite of mozzarella shell sandwiching a pillowy scoop of thick filling, or panna; the shell provided a pleasant contrast to the rich cream and kept the filling contained.

Salt Amplifies Burrata Flavor

In terms of flavor, the best burratas were milky, clean, salty, and fresh. One taster described our top-rated product as “mozzarella from heaven”; others proclaimed their love for the creamy, rich flavor of our favorite options. However, two of the burratas were relatively lackluster, with a plain milk flavor. Nutrition labels revealed that these products had just one-quarter to one-half the amount of salt of our favorite burratas—as little as 20 milligrams of salt per 1-ounce serving compared with 80 milligrams of salt in our winning burrata (which is on par with the sodium contents in our favorite fresh mozzarellas). A hearty dose of salt helped highlight the savoriness we love in burrata, while those with too little salt tasted dull and flat.

Our favorite was Lioni Burrata con Panna ($6.50 for 8 ounces). It was bright-tasting and nicely salted, with a thick, luscious cream that tasters loved. It was lauded for its “luxurious,” pillowy texture and fresh dairy flavor—proving that it is possible to get high-quality burrata from the supermarket.

Methodology

Twenty-one America's Test Kitchen staffers sampled four burrata products plain and in our Heirloom Tomato and Burrata Salad with Pangrattato and Basil. Sodium levels were taken from nutritional labels and were standardized for comparison, using a serving size of 1 ounce. Cream-to-shell ratios were calculated by separating the interior cream from the outer mozzarella shell, weighing each component, repeating the test for a total of three balls of burrata per product, and averaging results. Products were purchased in Boston-area supermarkets. Products appear below in order of preference.

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.

$4.49 for 18-oz. jar (25 cents per oz.)*

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."
