Once the chocolate has melted, remove the saucepan from the heat and stir in the extract. Then add the slivered almonds and mix well.
3/4 cup slivered almonds, 1 tsp almond extract
Pour/scoop the fudge into the prepared dish.
Place the fudge into the refrigerator to harden for 2-3 hours until set. Do not try to speed the process up by putting it in the freezer, it won't set if you freeze it.
Remove the fudge from the dish and carefully cut into small bite sized squares.
Notes
Store remaining fudge in an airtight container in the refrigerator for up to a week.
