All About Polish Cordials or Nalewki

An aged liqueur or cordial in Poland is known asnalewka (nah-LEF-kah) and nalewki when plural, and literally translates to "tincture."

Typically, they are made fruit, sugar, honey, molasses, herbs and spices macerated in vodka or rectified spirits known as spirytus rektyfikowany. Other flavors, like coffee, flower, honey, and specific spice nalewki likekardamonka (cardamom), also exist.

Nalewki names come from the type of main ingredient used to produce them or the town where they originated.

A popular nalewka named after a town is Nalewka Tarninówka, originating from the town of Tarnów near Kraków in Małopolska (Lesser Poland). It's made with sloe berries and is ruby red in color.

Many recipes are closely guarded secrets, passed down from generation to generation. The type of spirit used renders them either benign concoctions of about 40 to 45% alcohol or knock-your-socks-off varieties as strong as 75% alcohol.

Nalewka-Drinking Etiquette

Nalewki is always drunk from little glasses and often served after a meal, at celebratory occasions like weddings and baptisms. It would be an insult to your host if you bolted down a glass like a shot of vodka.

A nalewka should be sipped so that its virtues can be appreciated.

It should be allowed to linger on the tongue and then swirled around the mouth much like one would do with a fine wine.
