Meringue Cookies

So, I made these cookies and just looked back at the review from allrecipes.com (because that's where I found this recipe) and found a couple of different helps. So, if you aren't getting them to look like they should, just look at the reviews.

 Ingredients: 

2 egg whites
1/8 tsp salt
1/8 tsp cream of tartar
1 tsp vanilla extract
3/4 cup granulated sugar
1 cup semi-sweet chocolate chips.

Directions:

Preheat oven to 300 degrees F (150 degrees C). To prevent burning you can bake on an air cushion baking sheet or put parchment paper on a regular cookie sheet. 

Beat egg whites, salt, cream of tartar, and vanilla until very firm. Gradually add sugar and mix. Fold in chocolate chips.  

Drop by teaspoonfuls on (wax paper-lined) pan. Bake 300 degrees for 25 minutes. They should only be lightly browned.  

 So, as I was reading one of the reviews, I realized that after you add the sugar, it is supposed to still look like the egg mixture (first bowl picture) because one of the reviews said to never use a plastic bowl. Well, I only have plastic bowls. It doesn't actually matter what kind of bowls you use to make cookies. Just make sure your bowl is completely clean. :)
