Flavor profile

Walnut oil (Juglans regia) is approximately 63% linoleic acid (omega-6) and 13% alpha-linolenic acid (omega-3) — the highest omega-3 content of common nut oils, but also the most prone to oxidation and rancidity. Fresh, high-quality walnut oil from new-crop walnuts (particularly French walnut oil from Dordogne or Périgord) has a clean, gentle walnut character — slightly bitter, nutty, faintly astringent in a pleasant way. Store refrigerated and use within 2–3 months of opening. Always taste before using — rancid walnut oil (common in old or improperly stored bottles) is bitter, metallic, and unpleasant. The classic French vinaigrette with walnut oil (1 part walnut oil, 2–3 parts neutral oil, with sherry or red wine vinegar) dresses bitter greens (endive, radicchio, frisée) and pairs beautifully with Roquefort, pears, and walnuts. Walnut oil is also used in Périgord in preparations with foie gras and duck confit, where its regional affinity resonates with the local cuisine.
