Tiroler Erdäpfelgratin: thin slices of Austrian potatoes layered in an earthenware baking dish with garlic-infused cream, whole milk, nutmeg, and a crust of aged Austrian Bergkäse cheese.
In a saucepan, heat the double cream, milk, crushed garlic, nutmeg, salt, and pepper until warm and fragrant; do not boil.
Rub an earthenware gratin dish with butter. Layer the sliced potatoes neatly in overlapping shingle rows, scattering half the grated Bergkäse between layers.
Pour the warm seasoned cream mixture evenly over the layered potatoes, pressing gently so the potatoes are submerged.
Scatter the remaining Bergkäse over the top. Bake in an oven preheated to 180°C (160°C fan) for 45 to 50 minutes until the potatoes are knife-tender and the top is blistered golden brown.
