Can I use this mustard oil for frying or cooking at high temperatures?

Planeta Zdorovia Mustard Oil Oil King is specifically formulated and recommended for cold use only. The product documentation explicitly states that it should not be heated, as high temperatures reduce the valuable qualities of the oil and change its sensory character. Heating can degrade the fatty acid profile and diminish the distinctive pungent flavor that makes this oil unique.

Instead of using it for sautéing, roasting, or deep-frying, you should use it as a finishing oil. The best way to incorporate it into your meals is to drizzle it over dishes after they have been removed from heat. This preserves the oil's integrity and allows its rich, slightly spicy aroma to enhance the food without being destroyed by thermal processing. It is particularly effective when used as a dressing for salads, mixed into grain and vegetable bowls, or blended into cold sauces where its bold, expressive taste can shine through without being muted by cooking.

If you are looking for an oil to cook with, this product is not the right choice. It is intended to diversify your menu as a flavorful, unrefined plant fat source added in small amounts to cold or warm (not hot) dishes. Starting with a modest amount is advisable, as its flavor is more intense than neutral oils like sunflower or rapeseed oil.
