Preheat oven to 350° and line 2 baking sheets with parchment of silicone.
Pulse ½ cup almonds slices in food processor until ground. Transfer to a bowl and add flour, salt and remaining almond slices.
Combine suguar, butter, corn syrup and cream in microwaveable bowl. Heat on medium heat stirring every 30 seconds until mixture is uniformly melted and mixed. Heat 1 minute on high. (So mixture boils for 1 minute).
Add vanilla and orange pieces and stir till evenly combined. Mix wet mixture into the dry until well combined. All mixture to cool about 10 minutes until dough is cool enough to handle.
Using half the dough mixture, drop a generous teaspoon on to the baking sheet about 3 " apart. Mixture will spread.
Bake about 12 minutes until cookies are lightly golden. While cookies are baking drop the remaining batter on to the 2nd baking sheet.
Allow cookies to cool about 5 minutes before transferring to a cooling rack to finish cooling.
When cookies are completely cool, gently melt chocolate in a microwaveable bowl or cup on medium high heat. Stir every 20 seconds and be careful it doesn't burn. If using ½ cup of chocolate, take a spoon and drizzle chocolate over the cooled cookies tops. If using 1 cup of chocolate you can either dipp the edge of the cookie in the cup or brush the chocolate on the bottom of the cookie. Allow chocolate side up to cool completely.
Cookies will store in an airtight container in a cool place a couple of weeks. They also freeze and defrost well for one or two months. Ensure there is parchment paper between the layers of cookies when storing since they will be a bit sticky.
