ArrayList will not allow scanner input

I'm confused about something, again, in my code. I'm a beginner, but I still am familiar with the Scanner class. However, for a generic array, it bypasses the user input of a string. I want to understand why it's not being "collected" for the ArrayList:

public static void addingIngredients(){
    ArrayList<String> Ingredients = new ArrayList<String>();
    String addedIngredient = input.nextLine();
    Ingredients.add(addedIngredient);
    System.out.println(Ingredients +": Continue?" );
    System.out.println("1 (Yes) / 2 (No)");
    int choice = input.nextInt();
    switch (choice){
    case 1:
        addingIngredients();
    case 2:
        System.out.println("Test");
    }
}

The String "addedIngredient" is being skipped; This is what I'm receiving via console:

 Now Loading...
 What Ingredients are in this protein powder? 
 Begin Add?
 1 (Yes) / 2 (No)
 1
 []: Continue?
 1 (Yes) / 2 (No)
 1
[]: Continue?
1 (Yes) / 2 (No)
2
Test

Thank you in advance. P.S: Is there a more convenient way to write a loop to collect data from the user?

youre creating a new ArrayList with every call. you need to either use the same one of collect the results of each recursive call.

here's a simpler version you can start with:

ArrayList<> ingredients = ...
while (true) {
  //primpt for ingrediant, add to list
  if (endOfInput()) { //this is where you prompt for 1/2
     break;
  }
}
