Tempeh Goreng
Java, Indonesia (centuries-old Javanese soybean fermentation tradition)
Tempeh goreng — fried tempeh — is Indonesia's most nutritionally significant and culturally embedded protein: slabs of tempeh (whole cooked soybeans bound by white mycelium into a dense cake through Rhizopus oligosporus fermentation) marinated in coriander, garlic, turmeric, and salt, then deep-fried until golden and crisp. Tempeh originated in Java and is among the world's first intentional mould fermentations applied to a whole food protein. The fermentation of the soybeans reduces antinutrients significantly and produces a distinct nutty, slightly mushroom-like flavour with a meaty density that is fundamentally different from tofu. The frying caramelises the exterior while the interior remains firm but yielding; the entire slice is edible, including the white mycelium binding that becomes crisp.
