I am trying to add an element into an instance of array by using push(<<) to insert variables new_name and new_origin into ingredients array but I am receiving this error: undefined method `name’ for an instance of Array (NoMethodError)

There are two class instances – Menu and Ingredient

class Menu
    attr_accessor : dessert, :ingredients

    def initialize (dessert, ingredients)
           @dessert = dessert
           @ingredients = ingredients
    end
end

class Ingredient
    attr_accessor :name, :origin

    def initialize (name, origin)
           @name = name
           @origin = origin
    end
end

After a text file that contains Menu and ingredient information, I want to add a new ingredient information to the existing information.

Created arrays – menu and ingredient

menu = Menu.new(dessert, ingredients)
ingredient = Ingredient.new(name, origin)

Where error occurs
This below code: update the existing menu information
read_string is a function that display the prompt and return the read string.

#menus contains the read menu file information
def menu_update(menus)
  menu_id = read_integer_in_range("Enter the Menu to edit: ", 1, menus.length)
  menu_id = menu_id - 1
  ingredient_count = menus[menu_id].ingredients.length
  new_name = read_string("Enter a name for new ingredient: ")
  new_origin = read_string("Enter a origin for new ingredient: ")
  menus[menu_id].ingredients.name << new_name
  menus[menu_id].ingredients.origin << new_origin

  puts("Update info"
  puts("Name: #{menus[menu_id].ingredients[ingredient_count].name}")
  puts("Name: #{menus[menu_id].ingredients[ingredient_count].origin}")
end

Expected output:

Update info
Name: peanut
Location: USA
