For example, Marmite Crumpets don’t exist. You cannot buy them at the supermarket. To be clear: you can buy crumpets, you can buy marmite, you can buy butter; but you have to assemble them at home.
If you walk into a breakfast cafe, they will happily serve you sausage / egg / bacon / french toast / bubble / squeak (whatever that is). But no marmite crumpets. If you ask them to make it, they will give you a very strange look. It’s not typically offered. It’s something you just have to make at home.
It is unbuyable. Any tourist who comes to the UK to try a Marmite crumpet would need to bring a toaster or an oven with them, or quickly befriend a brit and hope that they have all the ingredients at home.
It’s not a secret. You just can’t have it.
*munches into crumpet thoughtfully, and salivates at the juicy savory delight, whilst staring at you pityingly and condescendingly*
Anyway, what’s something that I could never experience unless I made it myself in your local?
Avocado shake, at least in the western world. Unless you come across one at an asian shake/milktea shop, and even then, that menu item is rare.
How do you make it?
Shake an avocado till it’s ready
But you have to ask it nicely first
What is this defined as? I feel like we have them here, but they’re more like smoothies so I’m guessing this is different?
