[17] In Serbia, it is called orahovača, it is widely made in homes in the villages and is considered to be very good for health.

The green nuts are gathered in spring when they are green and soft enough to cut easily with a knife. The tannins give nocino its distinct flavor, but too much will make it too bitter for most people's tastes. Grain Alcohol It's often flavored with coffee beans, cinnamon or anise seeds but can also be left unsweetened and served as an after-dinner digestif. I have been using last year's nocino not only as a digestif but also as a swap-in for vanilla extract. Ingredients

Preparation – 20 minutes + a 3-month waiting period

The influence of process variables on phenolic content and composition of green walnut liqueur was studied. Alamprese and Pompei ( 2005) showed that temperature and length of steeping in ethanol had little effect on the phenolic composition of the liqueur. The total phenolic content of walnut liqueur was found to increase with increasing ethanol concentration (Jakopič et al. 2007). The antioxidant activity of GWL was shown to be in good correlation with the total phenol content that according to some authors remained unchanged during the storage (Alamprese et al. 2005). Spiced walnut liqueur is made from unripe, green walnuts. The spices and nuts give this liqueur a bitter-sweet herbal and aromatic taste that people especially enjoy around Christmas time. Usually, people in Austria will sip it neat. It’s smooth, drinkable and pleasantly aromatic, which is why people often times drink it after a heavy meal as digestif or to calm an upset stomach.

History:

The recipe for this walnut liqueur is from my cookbook ‘ Die Welt im Einmachglas‘ (in German). Variations from country to country Austrian-syle spiced walnut liqueur is dark brown, bitter-sweet, and aromatic. It is served neat. Gecer MK, Kan T, Gundogdu M, Ercisli S, Ilhan G, Sagbas HI.

The longer (and harder) way is simply allowing nature to take its course 🙂 Expert Tips + Recipe Notes Walnuts, like other tree nuts, must be processed and stored properly. Poor storage makes walnuts susceptible to insect and fungal mold infestations; the latter produces aflatoxin – a potent carcinogen. A batch that contains mold-infested walnuts should be entirely discarded. [2] Cosmulescu S, Trandafir I, Nour V, Ionica M, Tutulescu F.

[ CrossRef] [ Google Scholar]Place the walnuts, the alcohol, the cinnamon, the slightly crushed nutmeg, the cloves and the two types of coffee beans inside a large jar (like this) and close it tightly. Leave everything to infuse for 40 days, preferably in a sunny and airy place, remembering to mix once a week without ever opening the jar; Tip: The nuts stain strongly (dark brown), so I recommend wearing rubber gloves and using an old cutting board. After six weeks, add 300 grams of sugar to the mixture and give it another six weeks to rest. Shake the jar frequently so the sugar can dissolve in the liquid.
