Are there any cultural or regional variations in the preparation or consumption of paniņas?

What are paniņas?

Paniņas is the Latvian word for buttermilk. Traditional buttermilk is the liquid that remains when cream or soured milk is churned into butter. It is thinner than the cultured buttermilk sold in most supermarkets and has little fat. Older Latvian accounts mention buttermilk mainly in butter making: butter was washed until the water ran clear so that traces of buttermilk would not spoil it.

Are there regional variations?

We could not find a reliable source that describes distinct regional recipes for paniņas itself, so we do not list any. What is documented is the wider Latvian tradition of sour milk (rūgušpiens), and that does vary:

• Cottage cheese and bread were the most common additions to curdled milk.
• It was poured over cooked beans or peas, or over a roasted grain and legume mix that went by different names in different regions (kami, sutnes or pūtelis), often served with fried herring.
• It went into skābputra, a fermented barley porridge.
• Cold soup (aukstā zupa) is made with kefir, soured milk or buttermilk, beets, cucumbers, dill and boiled eggs, and in Latvia it is eaten with rye bread.

How to use buttermilk today

• As a drink: serve it cold, plain.
• In cold soup: often made with kefir or buttermilk.
• In baking: pancakes, quick breads and scones use the acidity of buttermilk; swap it for milk only if the recipe says so.

What to check on the label

Shop buttermilk is usually cultured, not the churn liquid. Look for the fat level, added sugar or flavoring, and the use-by date. Keep it refrigerated and smell it before use.

This is general guidance. If you have a family recipe from a specific Latvian region, trust it over any summary here.
