I got given a couple of goose eggs, I don't think I can find a bigger enough boiled egg holder ,but how long do I need to boil it for, so that it is soft but not raw but not hard boiled, I think there will be enough for you lot as well, when in got it i told my daughter the ducks layed it, gullable or what she thought they had.
One way of figuring it out is to weigh the egg, compare that to a hen's egg that you would boil for 3 minutes to soft boil. If the goose egg is three times the size that would give you 9 minutes.
I do love a goose egg. Tons of runny yolk... You'll need a whole squadron of soldiers to dunk!
My husband loved goose eggs. I used to boil them for around 8 to 10 minutes according to how big they were or how firm you want them. You need a very large egg-cup - I used a small cup with paper towels stuffed in the bottom. They have a season so make the most of them now.
