Their are basically 2 acceptable versions of scrambled eggs:
1) French – eggs are stirred continually and gently heated until fluffy and creamy. A dash of cream at the end to stop cooking
2) American – bit of butter and eggs are lightly fried with some stirring to give larger curds and some extra flavour from browning
With very careful microwaving (low power, lots of stopping to stir) it’s possible to do an ok version of #1. But you could do it quicker and better in a pan so really only for when there’s no hob.
Growing up we had nasty scrambled eggs with milk added so the liquid leached out after cooking. I think the milk adding was something my parents picked up from theirs, who started it during rationing to make the eggs go further. It’s an abomination.
