Pork Shoulder with Melted Apples and Celeriac Puree

With the recent gift to self of a dutch oven, I've been looking for and found beautiful things to make, including this one. I followed most of the recipe, however my rub of choice was thyme, rosemary, garlic and only 1 tbsp of salt.

As a side dish, celeriac puree (1 celery root and 1 potato) was a great, rich accompaniment.
