15-20mins? Wow! I actually thought it took longer to get it all cleaned up. You can definitely make it twice a week since it is not that time-consuming. Well, except if you have so many things on your plate that needs to get done. You know, my sister hates eating ducks (she has never eaten one) because of how messy they can be. "They are such dirty creatures", she will say.
Quite different to the really small eggs of geese... I hope to try the Duck egg someday...
