Grandpa's Chocolate Chip Cookies

Grandpa Andrus made these often, and they are still my favorite basic chocolate chip cookie recipe.

2 cups shortening (I substitute 1 cup coconut oil and 1 cup butter)
2 cups packed brown sugar
1 cup sugar
4 eggs
2 teaspoons vanilla
5 cups flour
2 teaspoons baking soda
1 1/2 teaspoons salt
12 ounces (2 cups) chocolate chips

Mix shortening and sugars together until well combined.  Add the eggs and vanilla.  Mix in dry ingredients and finally the chocolate chips.  Compact with hands if a little crumbly.  Bake at 350 for 10 minutes, or until golden brown.
