How to cook
Pour the flour in a wide bowl and make a well.
Add the ammonium bicarbonate, stir again and add spoonfuls of flour slowly until you obtain a thick sludge.
Once it becomes hard, pour it onto a floured counter and knead a medium-soft dough that doesn't stick. Divide it into 2 parts, roll out each into a rectangle.
Cut it into squares in turn, put 2 cherries from the jam and roll up into cigars. Arrange them in a tray with baking paper.
