Miso and lemon mousetraps

Do you remember mousetraps from when you were a kid? I couldn't wait to make them when the Small Girl was smaller, mainly so I could eat them myself. There's something about salty, savoury Marmite that goes so well with slightly scorched bread and cheese. But I've found something that goes even better - a mega-umami hit of miso. I know it sounds unlikely, but one bite and you'll be hooked. The only thing that makes it better is a squeeze of fresh lemon juice on top. Trust me, it's a winner.

The beauty of these mouth-watering morsels is that you can make a whole trayful to serve with drinks when  you are unexpectedly pressed into hostess service, or you can make a whole trayful and call it dinner on those nights when all you want to do is collapse on the sofa. You can use any kind of bread you like - baguette, a coarse-textured country loaf or even a cheeky gluten-free number, but nothing too wholegrain-y. Keep the slices about 1/2 a cm thick for best results and only toast one side so you get the soft/crunchy texture thing happening. I've kept quantities vague, but keep to the suggested ratio of miso to butter. Don't forget the lemon, either. Any leftover miso-butter mixture can be kept in a covered container in the fridge.

sliced bread, as above
1/2 cup white miso
1/4 cup unsalted butter, softened
50-100g tasty cheddar cheese, finely grated
1 juicy lemon

Preheat the grill and line a baking tray with foil or baking paper. Lie the slices of bread on top, then put under the grill until golden. Don't do what I do and wander off, unless you have an unlimited supply of bread to replace the charcoal that those forgotten slices will become. Take the tray out of the oven and turn the slices over, so the toasted side is facing down.
Put the miso and butter in a small bowl and mix until well combined. Generously spread the non-toasted side of the bread with this mixture, then scatter some grated cheese on top. Return the tray to the grill and toast until the cheese is crispy and the edges of the bread are darkening.
Let cool briefly before serving with a squeeze of lemon on top.  These are best eaten the day they are made.
