What You Need to Know
Tamarind's tartaric acid (C4H6O6) and turmeric's curcuminoids undergo pH-dependent solubility changes while fish proteins partially hydrolyze into free amino acids. The low pH environment (3.5-4.2) inhibits microbial growth while extracting hydrophilic compounds.
Achieves a signature 'clean sourness' distinct from coconut-based curries, allowing delicate seafood flavors to remain prominent.
