The book actually has many great and creative ideas. I also really love the puff pastry boats with various fillings, but have yet to make them. Some recipes allow them to be served at room temperature. She might be able to help you. Dunno but the label I looked at listed salt as the first ingredient.
Garlic salt is garlic powder blended with salt and a moisture-absorbing agent.
I'm not sure I see the logic to garlic salt and don't use it myself. After all, everyone has salt.
