I bought a tray of eggs (same ones as always) and upon cracking some of them I have found that there are quite a few that have 2 yolks inside. I used them as I regularly do but just wondered if any of you might have had the same thing happen and if yes did you count them as 1 or 2 eggs? I can't tell any difference in the cakes but am curious none the less.

One egg is one egg.

The only place where there could be a difference is if you are whipping the whites, then you will find that you need more of these eggs to make up the volume.

Slightly off topic, but amusing story. I had always been told that finding an egg with two yolks was good luck, and one would occasionally find a double yolked egg when we lived on a farm and raised our own or when we bought from local farmers, but I had never found one in a carton of store bought eggs. When I moved to Quebec and we celebrated our first easter there, imagine my surprise when I went to cook DH's easter breakfast and every egg I cracked was a double. I was so excited till I looked at the carton more closely and saw that it was labled as being double yolked. I don't know if that's peculiar to Quebec, but every easter I would see cartons of double yolked eggs in the stores there, and I've never seen them anywhere else.

Thanks
