Galangal

While both are rhizomes belonging to the ginger family, galangal (Alpinia galanga) has a noticeably sharper, more peppery flavor than standard ginger. It features distinct citrusy, earthy, and almost piney undertones, whereas ginger is warmer and simpler. You generally cannot substitute one for the other in traditional recipes without changing the dish's profile.

Galangal tastes much more peppery and astringent than regular ginger, with strong earthy and citrusy undertones. Some people also note a slight menthol or pine flavor when it is consumed. This robust flavor makes it a foundational seasoning in Southeast Asian curries and soups.

Galangal is a foundational seasoning in many Southeast Asian dishes, most notably Thai Tom Kha Gai (coconut soup) and various red and green curries. It is usually sliced or crushed into a paste with other aromatics like lemongrass and shallots. Indonesian and Malaysian cuisines also rely heavily on its sharp flavor for their regional spice blends.

While technically safe to eat raw, galangal is very tough, woody, and intensely peppery, making it quite unpleasant to chew on its own. In culinary applications, it is typically sliced into large chunks and steeped in broths, or finely pounded into a paste to release its oils. Diners generally remove the large slices before eating the final dish.
