A purist is one who desires that an item remain true to its essence and free from adulterating or diluting influences.
No gravy on my mashed potatoes please. Keep my salad dressing on the side. Don't mix make believe gooey cheese into my veggies and keep my burger plain. No vegetables from a can, no potatoes from a box, no instant rice and no powdered soup. I like to taste my food not the stuff all over it.
Oh, and hold the salt.
