Answer

Getting the products once we know what they are

There are two ways to bring up products on an arbitrary page in Shopify:

1) Using all_products[handle]

Using the product handle to get the product from the all_products global object.

Example:

{% assign ingredient = all_products['lavender-oil'] %}

This works well for small numbers of products, but for large numbers of products it may cause delays in page-loading times. We are also limited to only 20 (I think) calls to all_products per page, so this wouldn't work for recipes with a ton of ingredients in them.

2) Using a collection

Use a collection that contains only the products required. You can reference any arbitrary collection if you know the collection's handle. When making collections, you can also sort products manually to control the order that they appear in when you loop through it. Collections can contain an arbitrary number of products, and I believe the default pagination will give you is either the first 20 or 50 products if you don't specify any other limit. If required you can adjust the number of products served to as high as 1000 by wrapping your collection-product loop with paginate tags (though that upper limit is definitely not recommended for performance reasons)

Example:

{% assign ingredients = collections['love-potion-number-9'] %}
{% for product in ingredients.products %}
  <h2>{{ product.name }}!!</h2>
{% endfor %}

The downside for both of these is that you can't write Liquid code inside your article content in Shopify, so this ingredients section would need to be written as a snippet or a section in your theme files and included in your article template used for these recipes.

This leads me to consider the next issue - you would want to include a concept of quantity with the ingredients, and so far neither of the above give us that. So now, the hard part:

Getting that information into a Liquid snippet/section in the first place

There are a few different ways that I can think of offhand that would help you out here. No one is perfect, unfortunately.

Using Metafields

Metafields are a great tool available in Shopify, but unfortunately Shopify doesn't make them easy to use [1].

Once you have a metafield-editing tool, come up with a naming structure for the 'namespace' and 'key' values. For example, you might create the following metafields for the recipe you provided. (Note: How these would be entered will depend on what metafield-editing tool you're using)

namespace: 'ingredients',  // We'll use this as the 'box' that holds all our ingredients
key: 'juniper-berry-oil', // This will be the product handle for the product in question
value: '2 drops' // The quantity used for the recipe

namespace: 'ingredients',
key: 'rosemary-ct-camphor-oil',
value: '1 drop'

namespace: 'ingredients',
key: 'cypress-oil',
value: '1 drop'

... (etc) ...

Then, in your theme file where you are creating your ingredient list, you would have code that looks something like this:

{% assign ingredients = article.metafields.ingredients %}
{% for ingredient in ingredients %}
  {% assign handle = ingredient.first %}
  {% assign amount = ingredient.last %}
  {% assign product = all_products[handle] %}

  <!-- HTML code here -->

{% endfor %}

Using Tags and Products

If you create a tag-naming scheme, you can loop through those and use them to build your ingredient list. For example, if you give the article a number of tags in the form ingredient_[product-handle]_[amount], you would be able to reference them as:

{% for tag in article.tags %}
  {% if tag contains 'ingredient' %}
     {% assign breakdown = tag | split: '_' %}

     {% assign handle = breakdown[1] %}
     {% assign product = all_products[handle] %}

     {% assign amount = breakdown | last %}

     <!-- HTML Code -->
  {% endif %}
{% endfor %}

The downside to this method is that there's no easy way to reorder the tags if done this way - using a collection will give you better control of that.

Getting recipe amounts into a Collection loop

The easiest way to reference a collection would be to have a collection with the same handle as the article - then you can reference the collection and its products as:

{% assign ingredients = collections[article.handle] %}
{% for product in ingredients.products %}
   <!-- HTML Code here -->
{% endfor %}

This has the advantage of letting you easily sort the ingredients by setting the collection to have a Manual sorting method, but the corresponding downside is that there's no obvious place to put the quantity information.

One way to get that information in would be to use either tags or metafields - metafields would have the advantage of being able to directly access the quantity for the product - if using the naming convention above in the metafields part of this answer, you could use:

{% assign ingredients = collections[article.handle] %}
{% for product in ingredients.products %}
  {% assign amount = article.metafields.ingredients[product.handle] %}

  <!-- HTML Code here -->
{% endfor %}

If using tags, you would need a format that could be split up like in the tag section and loop through all your tags each time to find the one for your product. If your tags were set up as ingredient_[product-handle]_[amount]

If using tags, you would need a format that could be split up like in the tag section and loop through all your tags each time to find the one for your product. If your tags were set up as the example above:

{% for tag in article.tags %}
  {% if tag contains 'ingredient' and tag contains product.handle %}
     {% assign amount = tag | split: '_' | last %}
  {% endif %}

    <!-- HTML Code -->
{% endfor %}

Hopefully this helps you get going!

[1] Using Metafields: There are several possible solutions for editing metafields in Shopify - my personal preference is the 'Shopify FD' extension for Chrome, but the recent updates to the Shopify admin screens are interfering with this extension's ability to load & show its metafield panels on some pages. I know that product pages still work, but some pages (like collections) don't anymore.

There are also a number of apps available for your store to edit metafields - I haven't used any of them, so I can't speak to their value, but you can view the list here: https://apps.shopify.com/search?q=metafield&st_source=

If you have a coding background, you can also create and update metafields yourself by sending the right data to Shopify's Admin API - see the documentation at https://help.shopify.com/en/api/reference/metafield if you want to try doing it yourself.
