käsipuuro
Käsipuuro is a traditional Finnish porridge made from rye flour. The name translates to "hand porridge" or "hand-ground porridge," which likely refers to the historical method of preparing the rye flour by hand. It is a simple dish, often prepared with just rye flour and water, and sometimes a pinch of salt. The porridge is typically cooked until it thickens considerably, resulting in a dense and hearty consistency.
The preparation of käsipuuro usually involves gradually whisking rye flour into boiling water to prevent lumps.
