I bought this one mostly out of curiosity and came away thinking it deserves a permanent spot next to my regular finishing salts, not just as a novelty.
Where It Comes From
Sal de gusano is a traditional Oaxacan condiment, made by toasting and grinding chinicuiles, the red larvae that live inside agave plants, together with dried chiles and salt. The tradition goes back generations in the region and is closely tied to mezcal culture. Interestingly, these are not quite the same worms people picture floating in a bottle of tequila. That old bottle tradition, which was mostly a marketing gimmick anyway, typically used the white maguey worm, while sal de gusano is made from the red variety. Same general agave habitat, different worm. Rancho Gordo has theirs blended by Don Bugito, a Bay Area company that specializes in edible insects, which felt reassuring before I opened the jar.
What It Tastes Like
You will not taste worm, exactly. What comes through first is salinity, a lot of it, followed by a savory depth that reads almost meaty. The texture is extra fine, more like a powder than flaky finishing salt, which means it dissolves fast and coats whatever it touches evenly instead of sitting on top in clumps. There is a mild chile warmth underneath, but it stays in the background. The overall effect is less about heat and more about that umami quality everyone is looking for, the same rounding, savory depth you get from things like anchovy or aged cheese, just delivered through an ingredient list you would never guess.
Where It Pairs
This is where heirloom beans come in. I tried a pinch stirred into a finished pot of red beans, and it added a savory punch that plain salt cannot replicate, deepening the broth almost the way a good stock would, without any actual stock involved. It did just as well outside the bean pot. A light dusting over baked chicken right before serving gave it a savory undertone that regular salt alone does not provide, and it worked beautifully rubbed into a pork tenderloin as well.
I have not told Matt what is actually in this jar. He has eaten it three times now and has no complaints, so I am considering that a win. If the ingredient list gives you pause, I understand; mine did too. But this is one of those cases where the flavor argument wins. It is a genuine umami bomb in salt form, and a little goes a long way.
Where This Is Headed
Stepping back a bit, I think ingredients like this point toward where food is headed. Insects, seaweed, and hardy heirloom varieties keep coming up together in conversations about the future of what we eat, and not just because they can handle drought or tough growing conditions better than a lot of conventional crops. There is also a real case for diversifying and decentralizing where our food comes from, so that no single crop failure or disease outbreak can take down a huge share of the food supply at once. A pantry stocked with a few unusual, resilient ingredients feels like a small but genuine hedge against that kind of fragility, and honestly, it makes cooking more interesting in the meantime too.
