Filter Collection by category catSlug

I have a collection and have included categories that it can be tagged with. I want to be able to filter by these categories but can't seem to get it working. My code is:

<perch:categories id="categories" label="Categories" set="Recipes" order="7">
    <perch:before>
        <aside class="related-categories">
            <h3>
                Categories
            </h3>

            <ul>
    </perch:before>

    <li>
        <a href="/recipes?cat=<perch:category id="catSlug" />" rel="tag" itemprop="recipeCategory">
            <perch:category id="catTitle" />
        </a>
    </li>

    <perch:after>
            </ul>
        </aside>
    </perch:after>
</perch:categories>

and then on the collection page I am doing:

perch_collection('Recipes', [
    'filter' => 'categories',
    'match' => 'eq',
    'value' => perch_get('cat'),
]);

This results in no collection being matched. Could you tell me where I am going wrong with this? I tried filtering by categories[catSlug] also but seem to be clutching at straws with that!

Thanks

Use the dedicated category option to filter by category:

perch_collection('Recipes', [
    'category' => 'recipes/'.perch_get('cat'),
]);

Oh dear what a fool of me! I couldn't find that on the collection docs but have now found it in its dedicated section.

Thanks
