I was so excited to find this topic and discover I wasn't the only one longing for MerriMints. It took me a while but I finally tried all the ones mentioned here.
For me, Oliver's (http://www.oliverscandies.com/
) (the ones who make them for Vermont Country Store) comes closest. My box arrived with many of them fused together but that did not detract from the wonderful taste. They had the coolness I remembered and the "melt in your mouth" quality. The texture and taste seemed right on, too. Like Delamere I really missed the orange though. But the lemon's are heaven and all of them really reminded me of MerriMints.
I also tried Heberts (http://www.hebertcandies.com/
). Some were too mild, some were too artificial, the orange and lemon weren't minty, and the texture inside was wrong. The guy on the phone was very nice though.
And I tried Yummy's (http://yummies.com/store/mints.html
) which clbmd said were excellent. They are a tasty sugary treat but they are not "MerriMints" which is what I was looking for. They are msot like the french cream candies. I got Orange (since I was missing it from Oliver's) and Lemon (to compare to Oliver's). They aren't minty at all. They are too fat, they don't have ridges at the bottom, and they have sugar crystals outside. Like I said, a great treat but not MerriMints, which is what I am searching for. Also, some of mine were not only stuck together but sort of melted an squashed despite the packaging appearing to be intact.
Finally, I tried Sanborn's (http://www.sanbornscandies.com/candy.shtml
) which I don't remember being mentioned from this forum. I just ordered the Orange since you have to order by the pound and they didn't offer an assortment option on the web page. They were the right size, shape, texture but not minty and not orangey enough. They had fantastic packaging though
And all of the place listed above shipped very very quickly.
For my money (and memory) Oliver's is the place to go for the closest approximation to MerriMints. I'll be ordering a box with Orange next Christmas for sure. And, I know if I ever get to Batavia. NY I'll be stopping at Oliver's.
