Learning from a failing pistachio cookie experiment

 I tried to do the  trissalicious pistachio cookies recipe because I had the pistachios at hand and it seemed good. It was claiming it is the best pistachio cookie and it comes from all the way from Italy. I've been in Italy and it is delicious.

I am a very fearless baker and a cook, so substituting ingredients is not problem for me. I substituted  castor sugar with finely ground turbinado sugar and I also added almond extract. All was going great, It is a very quick and easy recipe.

The result was bad. The cookies were soft and a little burned  after being in the oven for just 7 min. I know I can not blame the recipe that I used because I did not followed it exactly. It was all my fault.

 Later I found out that turbinado sugar adds moisture and has more molasses that get burned quickly. These pistachio cookies tasted OK. Castor sugar is a specialty item that cannot be found easily. One can attempt to make castor sugar by grinding granulated sugar until it is super fine. Castor sugar cannot be substituted with powered sugar nor ground turbinado sugar, I know this from experience.

I would try the trissalicious pistachios cookie recipe again and see if I am successful.
