A dry mixture that crumbles when pressed gets a little more milk, and one that's too wet a few more crumbs.
Damp hands don't stick to the mixture, and the balls come out smooth and round.

Old-fashioned chocolate balls: 350 g finely crushed Petit Beurre biscuits, 50 g butter and 35 g bittersweet chocolate melted, 3 tablespoons cocoa, 3 tablespoons sugar and half a cup of milk; a dry mixture gets a little more milk, a wet one more crumbs.
Oat balls: a cup and a half of quick oats, half a cup of peanut butter and a quarter cup of date syrup mixed in a bowl, rolled with wet hands and chilled half an hour.
Log: put the mixture on parchment paper dusted with powdered sugar, shape with damp hands into a long log, roll the paper around it and freeze at least 3 hours; roll in the coating and slice.
