2. Slice off stalk and bottom ends of eggplant. Cut them lengthwise into ¼ inch (5mm) slices.
3. Place eggplant slices in a large bowl filled with salty water and leave to soak for 30 minutes, then remove eggplant from water and leave to dry well on paper towel.
4. Over medium heat, add ¼ cup (100ml) of olive oil to a large frying pan and fry the sliced potato in batches. Make sure to turn them over to cook both sides. The potato slices should be fried until slightly soft, about 4-5 minutes on each side.
5. When the potato slices are cooked, remove from the hot oil and place them on paper towels.
6. In the same frying pan, add ¼ cup (100ml) of olive oil and over a medium heat, start frying the eggplant slices in batches, adding olive oil regularly.
7. Remove each batch from the hot oil and place them on spread paper towels.
8. In the same pan, add ¼ cup (100ml) oil and sauté the diced onion until translucent. Add ground meat to the onions in the frying pan and mix well to break up the meat.

17. Spread remaining meat mixture out evenly to cover the eggplant layer. Using a spatula, press down gently on the layers to compact them.

White Sauce

1. Melt butter in a medium sized saucepan over a medium-low heat.
2. When butter is melted, thoroughly incorporate the flour in stages using a whisk and continuously stirring for about 5 minutes.

5. Add egg yolks slowly to the sauce, making sure to combine well.
6. Pour a thick layer of white sauce into baking pan to completely cover the top meat sauce layer. Spread white sauce evenly to ensure a uniform surface.
