Mix all the stuff together in a blender or large bowl until it’s smooth. Heat the griddle to ~180C/350F or heat a frying pan on medium heat. If you’re not using non-stick, grease the pan. Pour the batter onto the griddle/pan and swirl it around with the back of a spoon until you can’t – this stuff cooks pretty quick, so you’ve only got a few seconds before it stabilises, once it’s hot. Cook until the edges start to lift from the pan, and then carefully peel the crepe off and set it on a dish. This honestly makes a pretty ridiculous number of crepes, but I stopped counting at some point.
Shred the apples. Heat the butter in a frying pan until it’s melted. Add the apples. Add the spice. Cook until the apples have absorbed the butter and are soft. Move them into a bowl and mix in yoghurt.So, there. Like magic, fancy-ass food with a minimal investment of time, effort, and money. Takes like half an hour if you do it all yourself. I suggest making twice as much filling (or just using larger apples) and making the filling first, so you can chill it before serving it with fresh crepes. It’s also probably possible to make these with no milk, but if you do, I might advise adding a little cinnamon to the batter or like 1tsp of sugar, so they don’t taste like wallpaper paste.
