I want to make hard sugarfree liquorice bricks, what type of natural binder should I use? Thanks!

For my next artistic project I would like to build edible bricks in different shapes. Whereas I don't have a problem realising molds in differeny shapes and sizes, I don't kn ow where to start in order to have bricks that are hard enough, non sticky, possibly with a good fragrance/smell and that come with natural ingredients (not too many bad chemical things).
Also, I was thinking about liquorice, but they can also be made out of beetroot, cocoa, fruit juice etc.
They should last a good deal of days and possibly be eaten, although hard.

Make a hard candy using maltitol and unflavored sugarless syrup. Color and flavor just as you would with regular hard candy.
