Flavor profile

Walnut flavor is a combination of rich, fatty nuttiness from the high unsaturated fat content (65% fat, predominantly polyunsaturated omega-3 ALA) and variable bitterness from ellagitannins concentrated in the papery inner skin. The high PUFA content makes walnuts extremely prone to oxidative rancidity — stale walnuts are one of the most common examples of rancid food, with the unpleasant bitter-acrid taste of oxidized lipids. Fresh-shelled walnuts refrigerated or frozen are dramatically better than room-temperature walnuts in warm climates. Toasting (oven at 350°F/175°C for 8–10 minutes, until fragrant) reduces tannin bitterness slightly and develops roasted-nutty Maillard compounds. Black walnut (J. nigra, primarily North American) has a dramatically more intense, earthy, almost iodine-forward flavor compared to the milder English walnut. Walnut oil (cold-pressed) is one of the most flavorful finishing oils — used in French vinaigrettes, on salads, and drizzled on cheese. Classic preparations: walnut-raisin bread, baklava, green salads with roquefort, walnut pesto (pistou), and Persian cooking (fesenjan — the pomegranate-walnut sauce for duck and chicken).
