Gratin dauphinois recipe:

• Wash and peel the potatoes. Cut them into thin round slices without rinsing them, to preserve the potato starches.
• Rub the garlic in a gratin dish, then butter it.
• In a mixing bowl mix the egg yolks and cream.
• Season. Put a layer of potato on the gratin dish. Add some of the mixture. Lay a final layer of potato then pour out the rest of the mixture.
• Sprinkle with grated gruyère. Oven cook at 180° for around 1 hour and 15 minutes.
• Near the end of this time raise the oven temperature to make the gratin top golden.

Bon appetit!
