Fresh green walnuts are used to make preserves, pickles, and walnut liqueur, including Italian nocino. Their immature kernels can also be eaten, though they taste more astringent than mature walnuts; the firm green hull is usually prepared rather than eaten raw.
Yes, you can eat the soft kernel of a fresh green walnut raw before its shell hardens. It may taste bitter or astringent, and the tough green outer hull is generally not eaten raw; it is more often used in preserves or drinks.
Harvest fresh green walnuts while the shell inside is still soft enough for a skewer or knife to pass through easily. The exact season depends on the variety and climate, but they are typically picked in late spring or early summer for recipes such as nocino.
Nocino is made by steeping chopped fresh green walnuts in alcohol with spices and citrus peel, then straining and sweetening the infusion. Wear gloves when cutting the walnuts: their green hulls stain skin and cutting boards very dark.
Preserves are made by soaking fresh green walnuts to reduce their bitterness, then simmering them in syrup. Recipes vary: some use repeated water changes, while others include a lime-water stage. Wear gloves during preparation because the hulls stain.
The green husk of fresh green walnuts is not usually eaten on its own; it is bitter and rich in tannins. It is commonly cooked or steeped for preserves, pickles, or liqueur, while the soft kernel inside can be eaten.
Keep fresh green walnuts cool and dry, and use them promptly because the immature fruit can soften or spoil. For short-term storage, refrigerate them in a breathable container and check for mold, an off smell, or mushy spots before using.
Fresh green walnuts stain because their hulls contain dark natural pigments and tannins that cling to skin. Wear gloves while cutting or peeling them, and protect work surfaces; the marks can be difficult to remove once they set.
Yes, fresh green walnuts can be frozen, although thawing may soften their texture. Clean and dry them first, then freeze in an airtight container; use thawed walnuts in cooked recipes or infusions rather than expecting a crisp texture.
Fresh green walnuts can taste bitter and astringent, especially when the hull is included. Soaking and cooking help mellow the flavor in preserves and other recipes, while the soft kernel generally tastes milder than the green outer layer.

Fresh green walnuts are immature walnuts gathered while their outer husks are still green and the shells have not yet hardened. Their raw flesh can be strongly bitter and astringent, so they are more often preserved than eaten as a snack. In Turkey and parts of the Balkans, a classic use is walnut preserve, made by soaking and cooking the young nuts in syrup; they may also be pickled.
The preserve is served in small portions with tea or at breakfast, while pickled walnuts can accompany savoury dishes and cheese. These young nuts are notable for their fats and fibre, as well as omega-3 fats and polyphenols. If you try the sweet version, a little alongside plain yogurt makes for a less sugary-feeling serving.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
