Editor's note: A home baker can knock out chocolate chip cookies, a flaky pie crust, or a birthday cake that depicts a child’s favorite anime character. Macarons, however, are best left to the professionals, unless you relish weeping on your kitchen floor. For example, you must use powdered food coloring instead of liquid because even two drops of extra liquid can ruin the temperamental macaron’s texture. So while you’re Googling “best French bakeries in my area,” how about some lovely Macaron wallpapers?
