Swedish garlic and potato gratin: paper-thin King Edward potato slices baked slowly in garlic-infused double cream and sharp aged Västerbottensost cheese until meltingly tender with a golden crust.
Slice potatoes 3mm thin with a mandoline. Do NOT rinse in water, as natural potato starches create a silky sauce.
In a pot, warm cream, milk, grated garlic, salt, and pepper together until steamy and aromatic.
Layer sliced potatoes in a buttered baking dish, sprinkling 100g grated cheese between layers. Pour warm garlic cream over until potatoes are just submerged.
Top with remaining cheese. Bake at 190°C for 50-60 minutes until bubbling and potatoes are completely soft when tested with a knife. Rest 10 minutes before slicing.
