Since query results from the pg gem always return an array, you should do something like this to avoid having to reference the first item in the view like `@recipe_info[0]['description']`:

```ruby
  @recipe_info = db_connection do |conn|
    conn.exec(query, [selected]).first
  end
```

Then you can just reference it in the view with `@recipe_info['name']`
