how can I iterate through this array of hashes to receive a particular value : RUBY

the hash I have is the following:

aoh=[
  { "name": "Vesper",
    "glass": "martini",
    "category": "Before Dinner Cocktail",
    "ingredients": [
      { "unit": "cl",
        "amount": 6,
        "ingredient": "Gin" },
      { "unit": "cl",
        "amount": 1.5,
        "ingredient": "Vodka" },
      { "unit": "cl",
        "amount": 0.75,
        "ingredient": "Lillet Blonde" }
    ],
    "garnish": "Lemon twist",
    "preparation": "Shake and strain into a chilled cocktail glass." },
  { "name": "Bacardi",
    "glass": "martini",
    "category": "Before Dinner Cocktail",
    "ingredients": [
      { "unit": "cl",
        "amount": 4.5,
        "ingredient": "White rum",
        "label": "Bacardi White Rum" },
      { "unit": "cl",
        "amount": 2,
        "ingredient": "Lime juice" },
      { "unit": "cl",
        "amount": 1,
        "ingredient": "Syrup",
        "label": "Grenadine" }
    ],
    "preparation": "Shake with ice cubes. Strain into chilled cocktail glass." }]

How can I iterate through this to get JUST the ingredient (without returning name,glass,category,etc.)? I also need the same iteration for amount but I assume that will look just like the iteration for ingredient. Sorry for the dumb question, I'm new to ruby and have attempted this for hours now.

You have an array of two elements in your example. Those two elements are hashes with key/value pairs. You can loop through the array with the #each method and access the values that the :"ingredients" keys store like this:

aoh.each do |hash|
  hash[:ingredients]
end

The :ingredients keys each store another array of hashes. An example hash is:

{ "unit": "cl",
        "amount": 6,
        "ingredient": "Gin" }

You can then access the value under the :ingredient key by doing hash[:ingredient]. The final result looks something like this:

   aoh.each do |array_element|
    array_element[:ingredients].each do |ingredient|
      ingredient[:ingredient]
    end
  end

This currently only iterates through the arrays and hashes. If you want to also print the result you can do this:

  aoh.each do |array_element|
    array_element[:ingredients].each do |ingredient|
      puts ingredient[:ingredient]
    end
  end
#=> Gin
#   Vodka
#   Lillet Blonde
#   White rum
#   Lime juice
#   Syrup

If you want to get a modified array, you can use #map (or #flat_map). You can also get the amount with the value like this:

   aoh.flat_map do |array_element|
    array_element[:ingredients].map do |ingredient|
      [[ingredient[:ingredient], ingredient[:amount]]
    end
  end
#=> [["Gin", 6], ["Vodka", 1.5], ["Lillet Blonde", 0.75], ["White rum", 4.5], ["Lime juice", 2], ["Syrup", 1]]
