Liquid Smoke
We were among the many people who assume that there must be some kind of synthetic chemical chicanery going on in the making of "liquid smoke" flavoring. But according to the Colgin Company (which has been bottling liquid smoke since the 19th century), that's not the case. Liquid smoke is made by channeling smoke from smoldering wood chips through a condenser, which quickly cools the vapors, causing them to liquefy (just like the drops that form when you breathe on a piece of cold glass). The water-soluble flavor compounds in the smoke are trapped within this liquid, while the nonsoluble, carcinogenic tars and resins are removed by a series of filters, resulting in a clean, smoke-flavored liquid.
Curious about the manufacturing process for this product, we wondered if we could bottle up some smoke for ourselves. To do this, we created a small-scale mock-up of the commercial method, involving a kettle grill, a duct fan, a siphon, and an ice-chilled glass coil condenser.
In a comparison of homemade and store-bought liquid smoke, homemade was praised for its clean, intense, smoky flavor. But we spent an entire day and $50 on materials to produce 3 tablespoons of homemade liquid smoke. Commercial liquid smoke is just fine, especially if you avoid brands with additives such as salt, vinegar, and molasses. Our top-rated brand and contains nothing but smoke and water.

Columela Extra Virgin Olive OilOur favorite premium extra-virgin olive oil from a previous tasting, Columela is composed of a blend of intense Picual, mild Hojiblanca, Ocal, and Arbequina olives. This oil took top honors for its fruity flavor and excellent balance. Tasters praised its “big olive aroma, big olive taste” with a “buttery” flavor that is “sweet” and “full,” with a “peppery finish.” One taster said: “It’s very green and fresh—like a squeezed olive.” Another simply wrote: “Fantastic.” |

Bertolli Extra Virgin Olive OilA clear step down from the top oils, tasters noted “overall mild” flavor and “very little aroma,” with only a “hint of green olive” and a “hint of spiciness at the end.” In pasta, it was initially “not complex,” but gradually “bloomed in your mouth.” Overall, it was “worthy of a second bite.” |

Filippo Berio Extra Virgin Olive OilWhile some tasters found this oil “sweet” and “buttery” with “medium body” and “slight spice at the end,” others complained that it had “zero olive flavor” and was “so floral it’s almost like eating perfume”; still others noted a “bitter” aftertaste. In pasta, it was “extremely mild” to the point of being “boring.” |

Goya Extra Virgin Olive OilComments: The best comments tasters could muster were “mild” and “neutral.” Some liked it on pasta (though one called it “Snoozeville”), but complaints were myriad: “metallic,” “soapy,” “briny,” “hints of dirt.” Carped one taster, “I can’t imagine what is in here, but they have a nerve calling it EVOO.” |
