Ash Potatoes with Roasted Garlic Sauce and Mushrooms

First, marinate the egg yolks. Separate the eggs and carefully place the yolks in a small bowl. Mix the soy sauce with the water and pour the mixture over the egg yolks until they are almost completely covered. Let them marinate in the refrigerator for at least 2 hours.

Wash the potatoes but do not peel them. Place each potato between two wooden spoon handles and make deep cuts at regular intervals of a few millimeters (the spoons prevent cutting all the way through). In an oven-safe pan, melt the lard and toss the potatoes in it until they are coated with fat all over. Season with salt and bake uncovered in a preheated oven at 200°C (top/bottom heat) for approx. 50 minutes.

Cut off the tops of the garlic bulbs so that the individual cloves are visible. Wrap each bulb individually in aluminum foil and add them to the oven with the potatoes.
