Smoking salts

What it is

Salt cannot absorb smoke flavour through heat the way meat does, because there is no fat or protein to hold it. Yet smoked salt is unmistakably smoky, and the reason is that the salt crystals physically trap smoke particles on their vast surface area, a completely different mechanism from smoking food.

Smoking salts is the practice of exposing salt to wood smoke until it takes on a smoky aroma and a golden or brown tint. Coarse sea salt or flaky salt works best because its large, irregular crystals offer more surface for the smoke to cling to. The result is a finishing salt that adds a campfire depth to everything from roasted vegetables to chocolate, without any actual cooking over fire.

The method is slow and gentle. Cold smoking is ideal because heat would do nothing useful and could clump the salt, so the salt sits in a thin layer over smouldering wood chips for several hours, sometimes a full day, stirred occasionally for even colour. Different woods give different notes, hickory for strong and bacon-like, applewood for mild and sweet, oak for balanced. Most people start with a basic stovetop smoker or a foil pouch of chips and quickly find a wood they prefer. The honest trade-off is time, since proper smoking takes hours, but a single session makes enough finishing salt to last months and costs a fraction of the artisan jars in delis.
