We did a little taste comparison of US Mini Eggs (Hershey under license from Cadbury) to Canadian Mini Eggs (Cadbury Chocolate, Toronto) and I found the result surprising.
First the visuals.
The Candian Mini Eggs were darker in color, smaller, were a little pointier and were a smoother egg shape.
The US eggs were larger and lumpier and were more prone to those hairline fractures in the shell.
I expected them to be very much the same, but the difference in flavor were very apparent. The Candian eggs were much better, more chocolate flavor. In fact, after a Canadian egg and US egg tasted more like a creamy sweet thing than chocolate.
I also got some dark chocolate Mini Eggs (Royal Dark) in the US. The shell is darker and has a dusted appearance. The chocolate is smooth on the tongue but I have to admit I was a bit disappointed. When I eat these I mostly taste chocolate chips. There is a little bit of a nice warm finish to the chocolate flavor, but I have to wonder if there are dark chocolate Mini Eggs in Canada, and how much better the chocolate in those might be.
