Since we aren't making this cookie anymore, and it's not something I'd make at home, I did a quick internet search for images. I found this picture and copied and pasted, so I need to apologize to whoever I stole this picture from!
Lemon Meltaway Cookies
1 cup butter
½ cup powdered sugar
1 ½ tsp lemon juice
½ cup cornstarch
1 2/3 cup flour
Yellow food coloring, if desired
Cream butter/margarine and sugar. Add remaining ingredients and combine.
Bake at 350 for 9-10 minutes. Cookies are done when top starts to crack. Edges may be slightly browned.
Let cool completely.
To make icing, simply put some powdered sugar in a bowl, add some lemon juice and food coloring, mix until not lumpy. You can't mess this up, you can add more lemon juice to get the sugar not lumpy and if it ends up too runny, you can always add more powdered sugar.
Put on cookies with the back of a spoon and working gently, because these cookies are really tender, spread out.
