A potato gratin as a festive moonbase, complete with dome and landing platform.
A festive potato gratin, built as a round moonbase with an upright wall of potato slices and a dome of melted cheese. The silhouette refers to the astronauts' new lunar home: a recognizable moonbase on your plate.
Ingredients
- 1.2 kg waxy potatoes
- 250 ml heavy cream
- 150 ml whole milk
- 2 cloves garlic
- 100 g grated Gruyère
- 50 g Parmesan cheese
- 30 g unsalted butter
- salt and pepper to taste
- fresh chives for garnish
Method
- Preheat the oven to 180°C.
- Peel the potatoes and cut them into equal half-moon slices about 0.5 cm thick.
- Rub a round baking dish (24 cm diameter) with a cut clove of garlic and grease with butter.
- Stand the half potato slices upright along the edge of the dish to form a circular wall.
- Cover the bottom with a double layer of flat potato slices.
- Mix cream, milk, pressed garlic, salt, and pepper, and pour over the potatoes.
- Sprinkle with Gruyère and Parmesan cheese.
- Cover with foil and bake for 40 minutes.
- Remove the foil, add extra cheese in the center as a 'dome', and bake for another 20 minutes until golden brown.
- Let rest for 10 minutes, garnish with chives as an 'antenna', and serve.
Serving notes
- Serve in the baking dish so the round moonbase shape remains visible.
- Garnish with a tuft of chives in the center as an antenna.
- Cut into wedges so everyone gets a piece of moonbase.
