Wonton soup

Wonton soup looks simple but often contains several fermented or aged ingredients in the broth and filling.

• The broth — most wonton broths are seasoned with soy sauce or sometimes fish sauce, both of which are fermented and relatively high in histamine

• The filling — pork or prawn fillings are typically fine when very fresh, but minced meat sitting in a wrapper before cooking follows the same pattern as other ground meat dishes

A lightly seasoned broth with minimal soy and freshly made wontons tends to be easier going than heavily sauced restaurant versions.
