I am, probably, a beginner at cooking (can make a small variety of dishes well). Of late, I have been expanding my skill set and have been striving to reheat leftovers (no more than a day or two old) on stove.
For omelette leftovers, which I originally cook in butter, I add about half a tbsp butter for reheating. But it ends up oily in some places and dry in others.
Is there a particular amount of butter or other oil best for reheating omelettes? Should any liquids be added?
