Recap - Recipe Manager

You are managing a digital recipe book where each recipe is stored as a dictionary. Each dictionary contains the name of the recipe as the key and a list of ingredients as the value. Your task is to perform several operations to update and manage the recipe book.

1. Create the Recipe Book:
   Create a dictionary named recipe_book with the following recipes:
   • "Pancakes": ["flour", "milk", "eggs", "sugar"]
   • "Salad": ["lettuce", "tomato", "cucumber", "olive oil"]
2. Access Ingredients:
   Print the list of ingredients for "Pancakes".
3. Add a New Recipe:
   Add a new recipe "Smoothie" with the ingredients ["banana", "milk", "honey"] to the dictionary.
4. Modify a Recipe:
   Add "blueberries" to the "Smoothie" recipe.
5. Print All Recipes:
   Print the entire recipe_book dictionary to verify the updates.
