All you need for this winning winter warmer is some good sourdough bread, butter, Yarg (try both the nettled and the Wild Garlic) and a sprig of thyme or sage.
Put a frying pan on medium low heat.
Butter two slices of sourdough on both sides. Generously sandwich grated Yarg between and press.
Add butter, a splash of oil and the thyme to the pan.
Put the sandwich in the pan and fry until golden brown on both sides and the cheese is melted in the middle.
