Something curious happened this morning.
I wanted to have something sweet for breakfast, so made cocoa, and butterbrot. Cocoa was Dutch, the butter Ukrainian (only Cyrillic scribble on the packet), the bread was mine (I still bake them). When the first bite I took with the first sip it blasted me a memory of old with such strength I've never experienced. It reminded me that chocolate Leo icecream they were selling back in the Socialist era, and the taste felt perfectly the same.
I dunno what ratio and combination of the ingredients, and maybe whatever plus smell in the air that can influence how things taste was in that one bite with the sip of cocoa, but the rest of my meal wasn't close to that.
