Bake macaroons, 1 sheet at a time, until golden on bottom and browned in spots, 25 to 30 minutes. (Slide parchment paper off of the sheets, if you need to use the sheet for the next batch.) Cool completely on sheets.

For Glaze
Grate rind of 1/2 orange. Juice the 1/2 orange.
Melt margarine in small saucepan.
Whisk in Cocoa powder, water, orange juice and orange rind.
Add powdered sugar and whisk until smooth and the consistency of a melted chocolate.
