Fresh Coriander — the divisive herb that defines Indian garnishing
Fresh coriander (dhania, cilantro, Coriandrum sativum) is the most widely used fresh herb in Indian cooking — scattered over dal, curry, biryani, and chaat as a finishing green. It contributes brightness, freshness, and a distinctive aromatic character that no other herb fully replicates. It also divides people more dramatically than almost any other food ingredient — approximately 4–14% of people have a genetic variant that makes coriander taste like soap or cleaning fluid. This is not preference — it is hardware. Understanding both coriander's culinary role and the science of why some people cannot eat it provides a complete picture of this important ingredient.
Cooking Science
Why does coriander lose its flavour so quickly when cooked?
Coriander's primary aromatic compounds — decanal, dodecanal, and related aldehydes — are highly volatile with very low boiling points. They evaporate rapidly at cooking temperatures (above 100°C), carrying most of coriander's characteristic flavour with them into the kitchen air rather than remaining in the dish. Fresh coriander added to a boiling curry and simmered for 5 minutes loses 80–90% of its volatile aromatic compounds. This is why coriander is always a finishing herb — added off heat or in the final 30–60 seconds — never a cooking herb. Coriander seeds, which have different, more heat-stable compounds, are the cooking spice; fresh coriander leaves are the finishing aromatic.
Fresh Coriander — Correct Use
Why timing matters more than quantity
- Always add off heat or at the very end: scatter over the finished dish just before serving. The residual heat of the dish is enough to slightly wilt the coriander and release its aromatics without cooking them off.
- Both leaves and stems: the stems have more concentrated flavour than the leaves — use both. Chop stems finely; leave some leaves whole for visual appeal.
- In green chutney: blended raw — the aldehydes are captured in the chutney without cooking. Add lemon juice immediately to slow oxidation of the green colour.
- Storage: trim stems, stand in a glass of water (like flowers), cover loosely with a bag, refrigerate. Lasts 7–10 days. Or wrap in a damp cloth in the refrigerator. Do not store wet — promotes mould.

|---|---|---|
| Energy | 44 kcal | Very low — mostly water |
| Vitamin C | 135 mg | Excellent — major vitamin C source |
| Vitamin K | 310 mcg | Very high — one of the best dietary sources |
| Iron | 1.8 mg | Good for a leaf vegetable |
| Calcium | 67 mg | Moderate |
| Beta-carotene (Vitamin A) | 3450 mcg | Excellent |
| Folate | 62 mcg | Good |
| Typical garnish quantity | 5–10g | Nutritional contribution at this quantity modest but meaningful for Vit C and K |
Fresh coriander's vitamin C (135mg/100g) and vitamin K (310mcg/100g) are exceptional for a fresh herb. At typical garnish quantities (5–10g per dish), vitamin C contribution is 6–13mg per serving — meaningful given Indian cooking often destroys vitamin C in vegetables through prolonged cooking. Fresh coriander garnish preserves its vitamin C entirely. The beta-carotene content is also notable. Fresh coriander is nutritionally more valuable than its decorative role suggests.
