Bumping an old thread, but for future references.....
Lithuanian sausage is not made with onions. There is garlic, but not as much as in Polish. Less garlic and allspice is usually what makes the difference. AJ Meats use to make the best Lith. sausage, but since their "demise" a good alternative is :
S & T Provisions, a mostly Italian store but with various sausages. Their Irish Sausage is extremely close to AJ's Lith. taste. Racine is pretty good too.
