Add Parsnip (4) Golden Delicious Apple (2) Jerusalem Artichoke (12 ounce) Garlic (2 clove) Whole Milk (2 cup) Fresh Thyme (3 sprig) Bay Leaf (2) and a couple of pinches of Salt (to taste) to a medium pot and bring to a simmer.
Cover pot and reduce heat to low- simmer for 12-15 minutes, stirring here and there, until contents are soft.
Spoon contents into a high speed blender or food processor, excluding the thyme sprigs, bay leaves & excess milk.
Add Butter (2 tablespoon) and blend on high, adding some of the excess milk, 1 tablespoon at a time to achieve the right consistency, as necessary.
Once the puree is perfectly smooth, taste and adjust seasoning with salt
