Kale is the classic seasonal vegetable for winter. In smoothies and salads or prepared in the traditional way, it provides a hearty zest and a distinctive earthy, savory flavor.
In Northern Germany, kale is a fixed staple on the menu starting in October. Traditionally, this winter vegetable is served with smoked pork loin (Kassler), Mettwurst sausage, Pinkel (smoked groat sausage), or pork cheeks. However, the vegetable also tastes excellent in curries, stews, as a salad, or in a smoothie.
Peak season in December
Kale is a true German winter vegetable and can withstand temperatures as low as −15 degrees Celsius. However, it does not get its typical sweet taste from frost—lower temperatures simply slow down the plant's metabolism, causing more sugar to accumulate in the leaves. The longer kale ripens, the sweeter its flavor becomes. Sugar-rich kale varieties are therefore harvested as early as September, while the peak season is in December. Depending on the variety, the harvest ends in February or March. In Germany, Lower Saxony and North Rhine-Westphalia are known for kale cultivation.
Kale in the kitchen
Classic Northern German
Traditionally, kale is braised for a long time—with onions, mustard, broth, and a pinch of oat groats. It is served with smoked pork loin, Mettwurst sausage, or the famous Pinkel. A hearty winter dish that tastes best when enjoyed in good company.

Buying and storing
Fresh kale can be identified by its crisp, deep green leaves without any wilted spots. It keeps in the refrigerator for about 4–5 days. Tip: Remove the stems, cut the leaves into bite-sized pieces, and freeze them in portions after blanching—this way, you’ll have kale on hand even outside of the season.
