To make the fruit powders, place the freeze-dried fruit in a spice or coffee grinder, and pulse until very fine. If you notice a lot of big pieces still intact, sift the powder into the cookie dough.
If you want to decorate the cookies like this, melt some white chocolate (you can add a splash of vegetable oil if it's too thick to help thin it out). Pour into a plastic bag, snip a corner, and drizzle the chocolate onto the cookies. Sprinkle strawberry sugar (freeze-dried strawberry powder mixed with super-fine sugar) onto the chocolate and let harden.
