I came across an interresting tip for dealing with cookies--esp gf which
tend to be very delicate.

Line your cookie sheets with parchment paper which is available at
supermarkets and specialty stores.

For a drop cookie, try chilling the dough until easy to handle and then
put only a small amt ===scant teaspoon--on cookie sheet.  Bake as usual.

When cookie comes out of oven, slide entire parchment sheet off cookie
sheet onto counter and let cool.  Remove with sharp, thin, metal
spatula. If cookies stick, spray underside of parchment paper with water
and cookies will come right off.  Remove cookies to cooling rack to cool
completely,

I was amazed how few cookies I "lost" using this method.
