Kombucha-Glazed Salmon

Why This Kombucha-Glazed Salmon Works

As the kombucha, soy sauce, honey, garlic, and ginger simmer, the liquid slowly cooks down and thickens. Water boils off, the honey starts to concentrate, and the kombucha loses its sharp bite. After a while, the glaze becomes sticky enough to cling to a spoon, which means it will also cling to the salmon instead of running off into the grill.

Once the salmon hits the hot grill, the outside firms up and the surface dries just a bit. That dry surface lets the glaze stick in a thin, shiny layer. As more glaze is brushed on, it builds up and starts to bubble and darken, so the honey and sugars in the kombucha brown and form a light crust. Inside, the salmon stays moist because it cooks fairly quickly and is coated in that syrupy glaze, which slows down drying. By the time it comes off the grill, the fish is tender, and the glaze has set into a glossy coating that holds on instead of sliding off.

Mistakes To Avoid

Letting the kombucha glaze boil hard the whole time instead of simmering gently can cook off too much liquid and sugar too fast. The glaze then turns sticky and starts to burn in the pan, and later on the grill it scorches on the salmon before the fish is done, leaving a bitter, charred coating.

Putting the salmon over very high heat right away often burns the outside while the center stays undercooked. The glaze caramelizes too quickly, the surface goes dark and dry, and the fillets end up with a tough outer layer and a cold or raw middle.

Skipping the step of thickening the kombucha mixture long enough leaves the glaze too thin. On the grill it just runs off the salmon instead of clinging, so the fish comes off looking pale and wet, with a watery sauce pooling on the plate instead of a shiny, sticky coating.

Placing the salmon on un-oiled grill grates makes the skin and flesh weld to the metal. When it is time to flip, the fillets tear apart, leaving chunks stuck to the grill and giving ragged pieces of salmon with dry edges.
