Task: Question Answering
Input (English): I am on ketogenic diet, so eggs are like life saver. I always buy good quality eggs. Other day I bought some free roaming eggs from market. I want to make scrambled eggs. So first in a bowl I cracked 4 eggs one by one. Then with fork I whipped them for a while when they mixed very well, but did not overdo. I turned on my stove, put the nonstick pan on and  turned stove on medium heat. Meanwhile I got some cheese and salsa out for extra flavor. When the pan was hot enough, I added 2 tablespoon of unsalted  butter( I love butter), and then I did not wait it to be hot, but immediately poured my eggs into pan. The pan was already hot, so I started to bubble and cook. In a minute, I started to stir my eggs, added some cheese and salsa, salt and some pepper. I stirred the eggs till they became fluffy and cooked. When all moisture disappeared, I moved pan from stove, transferred it to plate. 
Question: What did they cook the eggs in?
Output (English): Butter and a non stick pan
