Absinthe has a lot of alcohol and a potent flavor. Before drinking it, you sweeten with a little sugar, and dilute it with a lot of water. There are several (rather theatrical) rituals for doing this, described in the wiki for Absinthe. Each variation of the ritual has its own equipment: Absinthiana.
The ortolan bunting is a small bird, cooked and eaten whole.
The birds are caught with nets set during their autumn migratory flight to Africa. They are then kept in covered cages or boxes. The birds react to the dark by gorging themselves on grain, usually millet seed, until they double their bulk. The birds are then thrown into a container of Armagnac, which both drowns and marinates the birds.[13][14]
The bird is roasted for eight minutes and then plucked. The consumer then places the bird feet first into their mouth while holding onto the bird’s head. The ortolan is then eaten whole, with or without the head, and the consumer spits out the larger bones. The traditional way French gourmands eat ortolans is to cover their heads and face with a large napkin or towel while consuming the bird. The purpose of the towel is debated. Some claim it is to retain the maximum aroma with the flavour as they consume the entire bird at once, others have stated “Tradition dictates that this is to shield – from God’s eyes – the shame of such a decadent and disgraceful act”,[13] and others have suggested the towel simply hides the consumers spitting out bones.
I have heard it claimed that in Viet Nam, helicopter pilots would order a cocktail that was set ablaze. Supposedly, you would stand on your head to drink it, because the skin of your chin is less vulnerable to fire than the mucous membranes of your nose. (Or, more importantly, your mustache.)
Holy Communion. As the kids in South Park put it, “We are going to church, so we can confess our sins and eat crackers.”
What other example are there, of food or beverages, where the ritual surrounding the thing is more interesting than the thing itself?
