Fluffy Tyrolean spinach dumplings simmered until tender, bathed in bubbling hazelnut brown butter infused with fresh sage leaves, and dusted with aged mountain cheese.
Combine the bread cubes with chopped spinach, milk, eggs, yolk, garlic, nutmeg, salt, and pepper. Rest for 15 minutes until cohesive.
Roll the mixture with damp hands into 6 compact dumplings.
Simmer in gently bubbling salted water for 14 minutes. Drain thoroughly.
In a skillet, melt butter until nutty brown and fragrant, frying the sage leaves until crisp. Pour over the hot spinach dumplings, dust with grated Bergkäse, and serve.
