My grandma had hundreds of recipes all in her head. She never once measured anything out. 

When she made cookies it was a little of this and a little of that.  So before she died we

all gave her the stuff that we liked the most, and for the next couple of months she put

togeather a cook book with all of our favorite recipes.  Everything we liked she would make and

write down how much of this and how much of that, so when she was gone we

could still enjoy her cooking.  Eveyone in the family got a copy of her cook book. 

My grandma has been gone now for 5 years, and that cook book is the most cherished thing in my kitchen.
