Either with clean hands or wearing rubber gloves, scoop out approximately 1 tbsp of mixture and roll into a ball then place onto the baking sheet. For bar shapes (like the originals) use 2 tbsp of mixture and roll into log shapes. If using silicon muffin cups, press 1 tbsp of mixture into the bottom of a mold and place on to a tray. If you are making on big block that you want to cut into bars you just need to press all of the mixture into the (lined) dish you are using. You can have the bars as thick or thin as you like, just remember if you are using a small tin/ dish the bars will be thicker and might take a longer time to chill.
