Color the marzipan orange either using orange food coloring paste or a mixture of yellow and red liquid food coloring (this is what I did).

Break off pieces of marzipan and roll into carrot-shapes.

Dampen a small knife and dip edge in cocoa powder. Carefully make indentations with the cocoa-dipped knife on the carrots to represent the soil. (You can also brush on the cocoa powder with a small brush).

Store carrots in a ziplock bag until ready to use.

Just before placing on desired dessert, use a round toothpick to insert a small hole in the top of the carrots. Slide in a piece of carrot frond.
