Vietnamese Salted Preserved Lemons (Chanh Muối)

Chanh Muối is an ancient Vietnamese preservation method that transforms lemons into a deep, umami-rich condiment. During weeks of brining, the rind softens and the bitterness fades, replaced by a complex salty-sour profile. Often used for 'Salty Lemonade' (a refreshing electrolyte drink) or in chicken dishes. Patience is key.
