Selecting Thai Aromatics
The foundation of a proper curry paste or tom yum broth lies entirely in the condition of your aromatics. Spend your time at the market examining the texture and scent of these raw ingredients before they hit the mortar.
Trust your eyes and your hands over labels.
Thai aromatics degrade quickly once harvested. You are looking for high-moisture specimens that still carry a sharp, distinct fragrance when nicked or bruised.

What goes in.
- 1 pieceGalangal: look for firm, cream-colored skin with minimal branching
- 3 stalksLemongrass: firm, tight bulbs that feel heavy for their size
- 1 handfulKaffir lime leaves: vibrant green, double-lobed, and leathery
- 5 piecesBird's eye chilies: taut, unblemished skin with vibrant color
Judging freshness by resistance
Apply firm thumb pressure to the base of the lemongrass or the surface of a galangal knob. If the ingredient gives way or feels hollow, it is dehydrated and will yield a muted, dusty flavor.
The method.
Select galangal
Choose knobs that feel heavy. Avoid sections that are shriveled or have soft, dark spots near the ends.
Select lemongrass
Peel back the very outer layer. The bulb underneath should be creamy white and smell sharp. If the stalk is yellowing or fraying, skip it.
Select kaffir lime leaves
Choose leaves that are dark green and have a waxy sheen. If you can bend the leaf without it cracking, it is fresh enough to release its oils during a simmer.
Select chilies
Check the stems. If the stem is brown or shriveled, the chili is old. Look for bright, taut skin that snaps clean when bent.
When it doesn't go to plan.
Store lemongrass by standing the stalks upright in a glass of water in the fridge.
Freeze kaffir lime leaves in an airtight bag; they maintain their aromatic profile for months this way.
When buying galangal, snap off the smaller 'fingers' to see the inside; it should be pale, fibrous, and smell like pine and citrus.
The ones that keep coming up.
Can I use ginger if I can't find galangal?
Ginger provides heat, but it lacks the earthy, medicinal scent of galangal. If you must substitute, use young ginger and expect a different flavor outcome.
Why do some lime leaves have holes?
Small holes in fresh leaves are common and usually indicate organic growing practices; as long as the leaf is firm and glossy, it is safe to use.
