I just now read through this thread out of curiosity. Geez, did the lore forum respond poorly to the thought of the Tsaesci, so far presented to us as a stereotypical asian culture, being given stereotypically asian food to eat. If you all are so averse to unoriginality how are you going to handle Dawnguard? Besides, there's no set lore on the matter, so what's the harm in reasonable speculation as long as it's not actively passed off as canon?
Fortune cookies, egg rolls, and rice are BATW
Why can't they be made interesting?
For instance:
"Of the sparse accounts of Tsaesci society, one constant across all subcultures is the fortune cookie, or
siiscin as they are natively called, gifted exclusively to foreigners and strangers to the Snake Palace. A mixture of flour, cane sugar, egg yolk, and blood paste pressed into saucer-like shapes and baked in closed mud or stone ovens, these delicacies are hand-made, as per custom, in a process that involves much time and effort. As such, their construction has come to be considered something of a high art, with reports of high status individuals visiting from surrounding nations receiving cookies bearing intricate swirls and designs, crafted by teams of the Potentate's own royal chefs.
The inside of the cookie itself is hollow and contains a fortune, traditionally written on papyrus, although poorer, more rural areas will inscribe the fortune onto a strip of the cook's own shed skin. The process of inserting the fortune into the sealed cookie is highly complex: the paper is actually mixed into the batter before baking. Therefore, the cuisinier cannot only be skilled in the culinary arts, but also adept at Tsaesci fang magicks, as he must create a space inside the cooking dough and maintain the temperature within so as not to destroy the fortune.
Interestingly enough, despite all the effort put into crafting the fortune cookies, there has never been a recorded instance of one actually being eaten. The recipient is always instructed to crack open the food beforehand, and to read the fortune inside before savouring the cookie actual. And the fortune is always the same: "You are being eaten". At which point, the gifted party is promptly devoured by the surrounding snakemen. Strangely, if the fortune cookie is refused the would-be prey is spared (for the moment, at least), allowing knowledgable or less-trusting travelers the chance to observe this ritual enacted on other, less lucky individuals. When questioned why they go to such lengths for such a simple treachery, the usual Tsaesci response, approximated to our tongue, is that it is for 'the sake of the dramatic'. "
