Walnut Oil

A delicate finishing oil pressed from walnuts — one of the few plant oils carrying meaningful plant omega-3 (ALA), with a brain-and-heart profile to match the nut's reputation.

Why it is ours

Black walnuts were foraged and cracked across Appalachia and the rural South, their oil and meat a wild harvest of the land. Walnut oil extends that tradition to the dressing and the finishing drizzle.

What it does

Walnut oil is one of the richest plant sources of ALA, the omega-3 the body partially converts to the EPA and DHA that quiet inflammation and protect the heart and brain. Its favorable omega-3-to-omega-6 ratio sets it apart from typical seed oils, which flood the diet with omega-6. The polyphenols and ellagic acid carried over from the nut add antioxidant and anti-inflammatory action. Because those omega-3 fats are fragile, walnut oil is a finishing oil — its benefit is real only if it is fresh and unheated.

How it is cooked

Use cold as a finishing drizzle over greens, beans, roasted vegetables, and grain bowls, or in dressings. Never cook with it — heat destroys the omega-3s and turns the oil bitter. Refrigerate after opening.
