Figs and walnuts are classic pairings and are especially good when made into grain-free snacks. Mixing Prune Bits into the fig paste adds an extra dimension to the treat, deepening the color and caramel flavoring for an alternative version.
Yield: one 25 x 5-cm [10 x 2-in.] log
In a food processor, pulse together the figs, prune bits, prune juice concentrate, and water until a paste forms. Transfer to a bowl and fold in the walnuts using a rubber spatula.
Lay out a sheet of plastic wrap. Shape the paste into a log and wrap in plastic wrap, twisting the ends tightly. Chill for 2 hours or overnight.
Slice through the plastic wrap into 6- to 12-mm [1/4- to 1/2-in.] coins, removing the plastic wrap before serving.
