Almond Paste

Based on: http://allrecipes.com/recipe/almond-paste/detail.aspx

I made almond pasted based on the above recipe, but with alterations suggested by merriwether9 (1 lb almonds, 3 cups powdered sugar, 2 egg whites). It was too sweet based on almond paste I have had in the past.

I had trouble getting the almonds to grind fine enough. My blender sort of gave up because it was sticking together, and it was like coarse sand. If I had a full size food processor that might have helped, but I don't have one so I'm not sure.

I will try this next time:
1 lb blanched almonds (just buy slivered almonds, they are pre-blanched)
2 cups powdered sugar
2 egg whites
1 tsp almond extract
