Olive oil and yoghurt...

"Life was simple, tranquil and often hard but despite the lack of modern amenities or even what was then available in the city, it was happy. There was no electricity or running water. We used kerosene lamps that gave poor lighting and kerosene stoves for cooking. The best stoves for indoor cooking were of the Swedish-made Primus or Radius brands. Weather-permitting, we cooked outdoors, often using a pottery pot, placed on three stones with a wood-fire underneath.

Food was tastier, simpler and healthier then, although we had no refrigerators. People dried fruits for the long, harsh winter, first by oiling them (which preserved tenderness) and then exposing them to the hot summer sun. Vegetables were sprayed with sea salt before drying. All our winter tomatoes were sun-dried, although nowadays that is a delicacy." (Thanks Marcy)
