@lgallus @boxystudio Here is what I’m doing to pull in recipe meta data.

Place this in your functions.php file

if (class_exists('Cooked_Plugin')) {
    add_action('rest_api_init', 'api_posts_meta_field');
    function api_posts_meta_field() {
        register_rest_field('cp_recipe', '_meta', array(
            'get_callback' => 'rest_get_post_meta',
            'schema' => null
        ));
    }

    function rest_get_post_meta($object) {
        $post_id = $object['id'];
        $post_meta = get_post_meta($post_id);
        $recipe_meta = array();

        if (isset($post_meta['_recipe_settings'])) {
            $post_meta_unserialized = unserialize($post_meta['_recipe_settings'][0]);

            foreach ($post_meta_unserialized as $k => $v) {
                if (in_array($k, array('difficulty_level', 'prep_time', 'cook_time', 'total_time', 'ingredients', 'directions', 'nutrition', 'gallery'))) {
                    $recipe_meta[$k] = $v;
                }
            }
        }

        return $recipe_meta;
    }
}
