First thing you want to do is to assemble the ingredients.
The second is preheat the oven to 235 degrees Fahrenheit.
Step 1: Ingredients
1 tsp. baking powder
1 cup granulated sugar
2 egg yolks
1 cup shortening
1 tsp. almond extract
1 tsp. vanilla extract
1 tsp. lemon extract
Now as for the 2 cups of flour you may actually want to use just a bit less than 2 cups otherwise the cookies will be harder to form and it's possible that not all of the flour will mix properly.
Make sure you are using baking Powder not baking Soda.
If your not sure how to separate yolks from whites in your eggs there are several ways. One easy way is to use a large slotted spoon. Crack the egg dump the messy bits into the spoon and hold over the sink. Next use a teaspoon to carefully slide up under the yolk (you don't want to pop the bugger). Turn, slightly, the spoon so that the edge carries the weight of the whites and like a very dull knife it will slowly cut through and you can drain off the clear bits leaving the yolk in whole. Mind you after a few attempts you'll have worked out some method that works for you.
Step 2: Preparing the Dry Ingredients
Sift together 2 cups flour and 1 tsp. baking powder in a small mixing bowl.
Easy enough yeah? Now the wet ingredients!
