I and my friend loved these growing up. In the 1990's this company went out of business and someone has decided to buy the name and attempt exploit it. I tried the Sour Lemons which were fairly good but and I FOOLISHLY assumed that these would be the same as before.
They are not the same as the original. Not only is the shape different, which is minor but the taste is not sour and not even palatable. I thought perhaps my roll got dunked in a cleaning solution so I tired another pack with the same taste. I gave a pack to a friend for his opinion and he agreed that these are not what we remember.
The best and closest you can get to the original Regal Crowns is the Jolly Rancher sour cherry.
