Preheat Oven to 350 and spray a large cookie sheet with pam

In small bowl mix dry ingredients
i.e flour, baking powder, salt

In a large bowl cream butter and sugar.

Add eggs and almond extract and mix well.

Mix the dry ingredients into the large bowl.

Split the dough in half and add your filling into each one and knead with your hands. You can also do a different filling for each one.

Flatten each loaf onto a cookie sheet; it should look like the shape of a gold bar.
Slather the beaten egg white all over these bars.

Bake for 35 minutes.
Slice immediately; but try not to make them too wide!
Then turn the biscotti over onto their sides and cook on each side for 7 minutes.
