Techniques
Amazonian cassava acid fermentation (piscado) uses lactic‑acid bacteria to lower pH, reduce cyanogenic glucosides, and preserve the tuber for communal consumption.
Fermented cassava acidifies and preserves fish, then the sealed product is heat‑sterilized at 121 °C for safety.
Smoke‑drying of fish in cedar frames reduces moisture and preserves nutrients.
Pit oven earth cooking uses slow, even heat transfer through packed earth to produce tender, flavorful dishes with a smoky, earthy profile.
Açaí juice undergoes spontaneous lactic‑acid fermentation at ambient temperatures, producing organic acids and enhancing antioxidant properties.
Cacao bean fermentation followed by stone grinding transforms raw beans into flavor precursors and a paste suitable for chocolate production.
Alkaline plant ash creates a hostile environment for microbes, preserving fish, meat, and tubers in Amazonian traditions.
Amazonian cassava fermentation uses spontaneous lactic acid bacteria to acidify the mash, hydrolyze cyanogenic glucosides, and gelatinize starch into a safe, semi‑solid product.
Maize starch extraction is a low‑temperature, water‑based process that isolates starch granules while preserving their native crystalline structure.
Amazonian cacao fermentation is a controlled, aerobic process that transforms pulp sugars into acids and ethanol, shaping chocolate flavor.
Guava jam fermentation is a low‑heat, biologically driven preservation method used by Indigenous peoples of the Amazon.
A low‑temperature smoking method that cures yuca roots with alkaline ash to detoxify cyanide before gentle smoking.
Cassava lactic fermentation converts cassava starch into lactic acid, reducing cyanogenic compounds and producing a sour, starchy food.
Steaming masa dough in banana leaves gelatinizes corn starch at ~100 °C, yielding a firm yet pliable texture with leaf‑derived aromatics.
Sapo is a traditional Amazonian fermented fish product made by fermenting fish in a plant-based brine at ambient temperatures.
Tapioca gelation is a thermal process where cassava starch granules absorb water, swell, and leach amylose to form a network that sets upon cooling.
Grated cassava is washed and fermented in a low‑salt brine at tropical temperatures, producing lactic acid that detoxifies cyanogenic glycosides and imparts a sour flavor.
