Place cream cheese, powder sugar and salt in bowel.
Begin mixing with hands till it forms a soft smooth ball. It will all mix in it just takes time.
Add mint oil with tip of tooth pic a little at a time. It is very strong and easily over done. Taste to adjust flavor.
Add paste food color of your choice or leave white if desired. Add the food color with tip of tooth pic also color is very concentrated and only takes a little. (I leave mine white because I will Pipe a decoration later).
Scatter a little corn starch on a flat wax paper covered surface and roll the mints out to about 1/8 inch thick. Use top of empty medicine bottle and cut circles out of mints. Re role the Mints between the circles till all is used up. Method 2 is roll the mint into 1/2 inch logs and cut across the log 1/2 inch lengths to make mint pillows. Then allow to dry 1-4 days.
Set mint circles aside to dry. Drying may take 1-4 days. Or you may begin to decorate with butter cream frosting and then allow to dry.. Mints will dry to a hard melt in your mouth texture.
