<span>Travel narratives and traditional fiction narratives are identical in purpose and format.</span>
I don't get what you're trying to ask but if you're asking what the food is, then it's Éclair.
In my opinion, the whole poem is quite ironic - although she is mentioning the exultation and the royal color of death, the poem itself begins with the narrator saying that she cannot breathe - that she doesn't want to die.
So, I would say that the ironic parts are:
Exultation is the going
Of an inland soul to sea, -
Past the houses, past the headlands,
<span>Into deep eternity!</span>
