Nested Irish eggs.
Well,
You make mashed potatoes,
You can use your own recipe of the one here.
When you are done.
You simply take the mashed potatoes and lay a mound on some buttered baking sheet and make a hole in the middle.
Then you throw in some peas.
Before you throw some in, for example I used frozen. So you warm them up in a frying pan with some butter till they are warm.
Then you break an egg on top. I didn't bother to beat the egg.
Throw the whole thing in the oven at 375.
20 minutes will be a little runny.
30 minutes will be hard like the above.
The mash potatoes will also start browning a little.
Then you move them from the baking sheet to the plate.
Voila, you are done.
Enjoy.
