What Is Walnut?
Walnut (Juglans regia) is the hard-shelled fruit of a tree from the Juglandaceae family; the edible part is the wrinkled, high-fat kernel inside this shell. Anatolia is one of the tree's natural growing areas, and walnut has been a familiar nut in Turkish cuisine for centuries.
Fresh (green) walnut is consumed for a short season, before the shell hardens, while dried walnut is available year-round as a nut with a long shelf life. It has a slightly bitter, oily, rich taste.
Nutritional Values of Walnut
Walnut is a nut with a high fat content but also high nutrient density; 100 g of kernel provides about 654 kcal of energy, 15.2 g of protein, and 65.2 g of fat. A significant part of this fat is omega-3 (ALA) fatty acid, which is rare among plant sources; it also carries fiber and various minerals.
What Are the Benefits of Walnut?
With its omega-3 fatty acid and fiber content, walnut stands out among the nuts that are part of a balanced diet. Studies on its contribution to plant-based omega-3 intake are ongoing; portion control is important because of its high calorie density.
This information is general; walnut is a food, not a substitute for medical treatment. Those with a nut allergy are advised to be careful.
How to Choose Walnut?
When buying walnut in the shell, checking its weight is the most practical method; shells that feel light generally indicate an empty or dried-out kernel.
- An in-shell walnut should feel heavy and full in the hand; avoid rattling, light ones.
- When buying shelled walnut kernels, the color should be vivid cream-beige; dark brown-black spots indicate rancidity.
- When smelled, there should be no moldy or bitter-oil smell; the smell of fresh walnut is mild and neutral.
How to Store Walnut?
In-shell walnut can be stored for months in a cool, dry, dark place; the shell protects the kernel from air and light to some extent. Shelled walnut kernels have a high fat content and go rancid quickly; in an airtight container in the refrigerator they keep their freshness for a few months, and even longer in the freezer.
Using Walnut in the Kitchen
Walnut is mostly consumed raw or lightly roasted; roasting noticeably intensifies its aroma. It is used across a wide range from sweet to savory: baklava filling, cake and cookie dough, walnut sauce, and salad topping are among its most common uses.
How Is Walnut Roasted?
Walnut kernels are roasted in a dry pan over medium heat for 2-3 minutes, stirred occasionally; they are taken off the heat once the scent intensifies and the color changes slightly. The time should be kept short, as over-roasting can lead to rancidity.
How Is Walnut Sauce Made?
Roasted walnuts, garlic, bread crumb, and olive oil are blended in a food processor to make the walnut sauce familiar in Black Sea cuisine; it is served alongside fish and vegetable dishes.
Which Recipes Use Walnut?
Walnut baklava, walnut cookies, walnut noodles (erişte), and salad with walnut sauce are among the most loved recipes. Roasted walnut pieces are also often used in soups and breakfast plates.
Frequently Asked Questions
What is walnut good for?
Walnut is rich in omega-3 fatty acid, protein, and fiber, and stands out among the nuts that are part of a balanced diet. It is a food; it does not claim to cure any disease.
How many walnuts should be eaten a day?
Since its calorie density is high, a handful a day (about 5-7 walnut kernels) is considered a reasonable portion. Since personal needs may vary, consulting a dietitian is best.
Why does walnut go rancid?
The unsaturated fats in walnut oxidize when exposed to air, creating a bitter taste. To slow this process, shelled walnut kernels should be stored in a cool, dark, airtight condition.
Should in-shell walnut or shelled walnut kernel be preferred?
In-shell walnut stays fresh longer thanks to the protective effect of the shell, but requires the effort of cracking. Shelled kernels are convenient but more prone to rancidity; the choice can be made based on how fast it will be consumed.
Is the green outer shell of walnut used?
The unripe walnut's green outer shell is traditionally used in jam and some regional beverages, but it has a strong dyeing property that darkens hands. Its common use in modern cuisine is limited.
