Tom kha gai (ต้มข่าไก่) is commonly introduced as chicken soup with coconut and galangal, but the name does not give the entire recipe. A Thai SELECT example recipe includes coconut milk, galangal, lemongrass, chicken, mushrooms, makrut lime leaves, fish sauce, lime and chili. It is an example that helps explain the dish, not proof that every restaurant uses those ingredients or the same amount of chili.
What should a visitor learn from the menu?
Begin with the food type and the ingredients that define this kitchen's serving, such as “chicken soup in a coconut broth scented with galangal”. Then name the mushrooms or herbs actually included and describe the taste of the current recipe. If the kitchen offers a different broth, a vegetarian variation or a choice of protein, give each real option a clear label and price. A photograph should represent the regular serving, not a more elaborate sample made only for marketing.
Do not assume the soup is mild or fish-free
The Thai SELECT example contains both chili and fish sauce, so “mild and fish-free” would be a poor automatic translation. A particular restaurant may use less chili or another seasoning; only its cook can confirm that. Ask how the usual bowl tastes and whether chili can actually be adjusted. If staff are unsure, avoid a numerical spice score that appears more precise than the kitchen's information. A customer concerned about fish or another ingredient needs a recipe check, not an inference from the name.
Check ingredients and preparation for allergy questions
Verify the current coconut product, sauces, seasonings, garnish and prepared components against the recipe and supplier labels. Ask about possible cross-contact through shared utensils or preparation areas before answering a specific allergy question. Coconut broth is not a general assurance that there is no dairy, fish or other ingredient in the finished bowl. The allergen-information guide explains how to keep the menu team's evidence traceable; it is not a kitchen safety certificate.
A menu sentence to adapt, not copy blindly
Try: “Tom kha gai — chicken soup in [the shop's coconut broth], scented with [the herbs actually used], served with [the real additions].” Replace every bracket with verified facts; remove anything the kitchen does not use. State the current portion, price and heat according to the shop's serving. Compare with the tom yum goong explanation if both soups appear on the menu, but describe each real bowl rather than claiming their only difference is heat. Keep the Thai, English and Chinese versions consistent when the recipe changes.
