Olive oil is expensive and currently rare: you can use it instead for salads and for frying. Recently, weather conditions, including drought, have led to crop failures.
If you don't want to dig deeper into your wallet, you can look for alternatives. Cold-pressed oils are more suitable for cold cuisine and refined oils for hot cuisine. You can also fry with margarine, which can be heated to as high a temperature as the oil it is made of. The Tagesschau reports that olive oil prices rose by 43.5 percent in November compared to the previous month.
