As a kid (over 40 years ago yikes ) my aunt would regularly bring me a tin of butter mint candy. The candies were off white kind of yellowish, football shaped but flat on two sides. Maybe a 1/2 inch long. It was a soft candy. The candies were not wrapped. They came in a flat round maybe 10 inches or so in diameter. If I remember correctly, the tin was off white or yellowish too.
I can't remember the brand name.
Does anyone remember these candies? They were probably horrible for your health but they were delicious. I have looked in a number of candy stores for these mints and have not been able to find them. A search of the internet brings up those horrible wrapped hard mints you usually get at weddings.
