These are very tasty! I browned them a bit too much - and they ended up tasting like perfectly roasted marshmellows! My husband and I ate the whole batch standing over the cookie sheet - oops.
I used a temp of 325 F. We're high altitude, so we have to reduce temps. Browned too much and spread out after 5 minutes. Took out immediately. Will try to eat them, but....... I would suggest 300 degrees.
Yum! It does taste like Marshmellows! but I didnt have the parchment baking sheet so i used foil with a little bit of cooking spray it spread so much and was all over the place, but it tastes really good!
Made a slight change with the recipe. Instead of whizzing the egg whites until white, I just did it for about 15 seconds and added the sugar. Blended them together until white and creamy. Then added the lemon juice, plus a pinch of salt and 1/2 tbsp of whole wheat pastry flour. Mixed those ingredients together, then put them on parchment paper and cooked same as normal recipe. Looked really nice in the oven, but as soon as they started cooling, immediately deflated to little flat, wrinkly things. Other than that, tasted awesome! Really close to marshmallows. My siblings and I loved them!
