Día de la Pachamama: The Peruvian Ritual Behind Tokosh

August 1, 2026

Today, August 1, communities across the Andean highlands of Peru, Bolivia, and Ecuador mark Día de la Pachamama. If you've never heard of it, the short version is this: people pour out the first drops of their chicha or beer onto the ground before drinking it themselves. They bury small offerings, coca leaves, sweets, flowers, sometimes a coin, as a way of thanking the earth for what it gives. Locals call the ritual a "challa," and the whole month of August is loosely considered Pachamama's month in parts of the highlands.

The idea behind it is a Quechua concept called ayni: reciprocity. Whatever you take from the earth, you're supposed to give something back. It's not really a religious holiday in the way a lot of Americans might picture one. It's closer to a working relationship. You don't just extract from the soil and walk away. You feed it too.

I bring this up because we sell a product that, in its own strange way, lives out that same principle every single day it's made: tokosh.

A food that goes back into the ground on purpose

Tokosh (sometimes spelled tocosh) is one of the oldest preserved foods in the Andes, and the process is almost the opposite of what you'd expect from a "superfood." Farmers take potatoes and submerge them in cold, running spring water, usually somewhere with a steady current, for weeks at a time. Depending on the water temperature, fermentation can take anywhere from 20 to 30 days, though some batches are left for months, even up to a year, before they're pulled out.

During that time, naturally occurring lactic acid bacteria go to work on the starches in the potato. The potatoes darken, soften, and take on a strong smell that, by most accounts, is not for the faint of nose. Once fermentation is done, they're pulled out, sun-dried, and ground into the powder we sell. The name itself comes from the Quechua word togosh, which roughly means "wrinkled," and that's exactly what the dried result looks like.

This isn't a niche or recent trend. Quechua communities in the central Peruvian highlands have made tokosh this way for generations, largely as a way to preserve potatoes through the harsh dry season and to have something reliably gentle on the stomach when someone in the family was sick.

You'll sometimes read that tokosh contains natural antibiotic compounds, occasionally with the word "penicillin" thrown around. We want to be straightforward about that: this is a popular claim repeated a lot online, but we haven't found solid clinical research confirming it, and we're not going to repeat it as fact. What does have some backing is the general idea that lactic acid fermentation produces probiotic bacteria and can make certain nutrients easier for your body to absorb. That's a real, well-documented mechanism in fermented foods generally. Whether tokosh specifically delivers meaningful digestive benefits in the amounts people typically use it (a spoonful stirred into a smoothie or soup) hasn't been studied in the kind of controlled human trials that would let us say much more than that.

Why Pachamama Day made us think of it

We're not claiming tokosh is a Pachamama Day food in any formal sense. It's not part of the challa ritual, and nobody we know serves it as an offering. But there's something about the process that echoes the same idea behind the holiday. You don't rush tokosh. You give the potatoes back to the water and the cold mountain air, and you wait for weeks, trusting a slow, unglamorous process instead of forcing an outcome. It's the same patience behind letting the earth do what it does before you ask anything of it.

If you want a more literal Pachamama Day connection, that's actually purple corn. Chicha morada, the purple corn drink poured out in a lot of challa ceremonies, comes from the same maíz morado we sell as a powder for making the drink at home. Between the two, tokosh and chicha morada probably come closer than anything else in our shop to what's actually on an Andean table this week.

What it actually tastes like, and how people use it

We'll be honest: tokosh has a strong, funky, faintly cheesy-sour smell that catches most first-time buyers off guard. The taste, once it's cooked into something, is milder than the smell suggests, especially blended into a soup or porridge, which is the traditional way it's eaten (often as "mazamorra de tocosh," a warm pudding-like dish). A smaller pinch stirred into a smoothie is a more approachable starting point if you're new to it.

A few practical notes if you're trying it for the first time. Start with a small amount, maybe half a teaspoon, and see how your stomach handles it before working up to a full serving. Because it's a fermented food, people with histamine sensitivity or a diagnosed FODMAP intolerance should be cautious and talk to a doctor first. The same goes if you're pregnant, nursing, or managing a chronic digestive condition. It's a traditional food, not a medication, and it isn't a substitute for medical care.

If tokosh feels like too big a leap, our Moringa Powder is a gentler, more neutral-tasting way to add a nutrient-dense Peruvian superfood powder to a smoothie. And if the earth-offering angle is what pulled you in, our Purple Corn Powder is the actual ingredient behind the drink poured out during this week's challa ceremonies.
