Green food colouring (start with a couple of drops, then add more until you achieve desired colour)
4 cups (500g) icing sugar
10 oz chocolate candy coating (I used Wilton's Candy Melts Light Cocoa)
In a medium bowl, stir together the corn syrup, butter, extract, salt, and food coloring until well combined.
Mix in 1 cup of icing sugar at a time until mixture is too stiff to stir. Add more icing sugar and knead mixture until it no longer sticks to your hands, adding more icing sugar as necessary.
Roll into 1-inch balls and place on trays or baking sheets lined with waxed paper. Flatten with a cup or your hand. Cover with another sheet of waxed paper and refrigerate for 60-90 minutes or until firm.
Melt chocolate candy coating according to package directions.
Dip the candies into the melted chocolate with a fork, tap off the extra, and place back on the waxed paper. Repeat until all candies have been coated.
Let candies set up until chocolate is firm before storing in an airtight container.
Candies can be frozen in single layers separated by waxed paper if desired.
