Hello from the Netherlands!
My sweetie is from Lithuania originally, she's been living here with me for nearly 27 years now. But why are Grandmothers wrong?
When my gal was young she hated (and still hates!) cooking, her Grandmother told her repeatedly that she would have trouble finding a husband if she never learned to cook!
Well here we are, 27 happy years together later .... and this weekend I made my girl Šaltibarščiai. And very tasty it was too :)
Now I'll admit I made it with roasted beetroots instead of boiled or pickled (I prefer the flavor, sorry to the purists), and the potatoes I also made in my preferred style (skin in, parboiled and then roasted in the oven with olive oil) - so just a touch different to the way you folks have them .... but in any case she never did need to learn to cook :)
Our Dutch friends who were over for dinner also were very surprised by one of your favored dishes and wanted the recipe too :)
Have a great evening!
