Answer:
1. base,bread,toast,cracker,puff pastry
2. fish
Explanation:
Passed appetizers are formed with a base and a topping/garnish.
The base can be made of various types of support elements for the garnish. Traditionally it's some form of bread or baked product.
So, first blank spot would be:
you will need a _base,bread,toast,cracker,puff pastry__ ,
Then on top of that base you place some garnish/topping. It has to have some form of proteins in there. Since the question mentions Dorothy has some leftover salmon... let's assume she'll use it.
then your__fish_ and garnish.
