Walnuts
Rich, earthy, mildly bitter, and oily with a slight astringency — flavor deepens and sweetens when toasted.
Lens analyzedWalnuts are earthy, slightly bitter tree nuts with a rich, oily texture and a mild astringent edge. They add crunch, richness, and a distinctive flavor to baked goods, salads, pasta sauces, and snack mixes.
Where it comes from
Walnuts are one of the oldest tree nuts consumed by humans, with Persian walnuts first cultivated in ancient Persia before spreading throughout Europe along trade routes. English walnuts — the common supermarket variety — are now grown widely in California and are a pantry staple in North American baking.
Varieties — English (Persian) walnuts are the common North American variety; black walnuts are native to North America with a more intense, earthy flavor.
Walnuts appear in Persian and Middle Eastern cooking (walnut sauces, stuffings), Ligurian walnut pesto in Italian cooking, and throughout European and North American baking.
In a modern kitchen — Toasting walnuts in a dry pan for a few minutes deepens their flavor and reduces some of the bitterness.
Buying it
Buy shelled walnuts that look plump and golden-yellow inside, not shriveled or dark. Walnuts go rancid faster than many nuts because of their high oil content — buy in small quantities and store in the refrigerator or freezer.
Storing it
Store in a sealed container in a cool, dark spot — their oils turn rancid faster than most nuts, especially in a warm kitchen. For longer freshness, keep them in the fridge or freezer instead.
Keeps about 6 months in the pantry.
Out of walnuts? Good swaps
- Pecans — Sweeter and less bitter; substitute one-for-one in most baking and salads.
- Chopped almonds — Less oily and more neutral; works in most baking applications.
- Hazelnuts — More distinctly flavored; good in chocolate desserts and salads.
