Place sugar, chocolate and milk in a heavy-based saucepan
and heat, stirring until melted and smooth. Bring to a boil
and boil, without stirring, until mixture reaches 234 to
240 on a candy thermometer. Remove from the heat and let
cool for 5 minutes. Gradually stir in the margarine, in
small pieces, until melted and mixture is smooth. Let cool
for 30 minutes.
Add the vanilla and beat well. Pour into a prepared 8"
square pan. Let harden slightly before marking into 1"
squares. Leave in the pan until completely set.
