Last time when I visit my friend, her daughter made these sweet balls; they left a big impression on me, even more, when I made them for the first time. They are easy to make and you can keep them and serve straight from the freezer. —anka
Grind the nuts with a nut grinder; hard cheese grinder is second in the line to do the job. Put on the side.
Ground biscuits in a food processor or blender; just break them first in smaller pieces. You can also place biscuit between to parchment paper or plastic bag and use the rolling pin to break them into powder.
Boil sugar and water till sugar dissolve, take off the stove and mix in ground biscuit and 150 g ground walnuts. Let it completely cool.
In meantime; cut off the stem of the fig and using the tip of the paring knife make a slit where the stem was.
Insert walnut halve into fig and press to close, it is sticky so it will hold together.
Take completely cold walnut-biscuit mix and apply all over fig in a thin layer, roll between the palm of your hands and then into a ground walnut. Roll rest of the figs.
Place in the freezer for 1 hour. To serve you will cut them in half; it is easier to cut when they are frozen.
You can keep them in the freezer, in an airtight container for a couple months.
