Of course, this is not enough. Because natural sodium saltpeter may also contain impurities such as magnesium ions and calcium ions, which are difficult to separate.
Therefore, further treatment is required. For example, Marin remembers a good way for the Ming Dynasty to purify saltpeter - saltpeter and radish are cooked together. Then, the adsorption properties of the radish can be used to further adsorb and remove magnesium and calcium ions to achieve the purpose of purification. The saltpeter treated in this way is not easy to dehydrate. If it is stored in a sealed oil paper bag, it can be stored for a long time...
"Yes, I almost forgot about the carrot!"
Marin slapped his head and remembered the sacks of carrot seeds he brought back. This is a magical tool. It can not only purify saltpeter, but also remove the smell of goat milk. It is absolutely omnipotent.
Just in time, radishes can still be grown in late spring and early summer. After all, the growth cycle of radishes is very short, only two months. After two months, a large number of radishes can be produced.
Radishes not only have a short growth cycle, but also have a large yield. Especially for large white radishes, the yield per mu can reach a huge amount of ten thousand jin. Of course, the white radish varieties in this era may not be that powerful, and the yield per mu is not that high. However, it is still okay to have a yield per mu of two or three thousand jin.
Moreover, radishes can be grown for two or three seasons a year, and the total yield is higher. Compared with potatoes and sweet potatoes, radishes are the overlords of the yield world.
But unfortunately, radishes cannot be used as staple food, otherwise they can crush potatoes and sweet potatoes.
However, although it cannot be used as a staple food, it is also a very good vegetable. Marin remembers that in the later years, before the rise of greenhouse vegetables in the north, they lived on cabbage and radish as vegetables in winter. Every winter, the vegetable cellars of northerners were filled with cabbage and radish.
Moreover, radishes can be marinated into dried salted radishes, which can be preserved for a long time and serve as a complementary food for staple food. For example, when drinking porridge or eating steamed buns, it is also good to eat some dried radishes.
In fact, because there are no radishes and cabbage in Europe, there is a very lack of vegetables in winter. Marin thought about it and decided to vigorously promote the cultivation of carrots and cabbage in Beihai Kingdom (he also brought a lot of Chinese cabbage seeds back).
Then, Marin asked Angela to come forward and asked him to send people to reclaim large wastelands for growing carrots and cabbage.
At the same time, each manor is divided into a small number of areas for growing radish and cabbage.
In this way, in the future, serfs in each manor can also eat two preservative vegetables, cabbage and radish, in winter. If it really doesn't work, you can also pickle the radish into dried salted radish and pickle cabbage into sauerkraut. For specific pickling methods, Malin has brought two Ming dynasty women back and specially guided farmers to pickle dried radish and sauerkraut.
...
In fact, radishes are used not only to purify saltpeter, absorb the smell of sheep, and to cook or pickle.
Because radishes can be grown almost three or four seasons a year, and the yield is large. In addition to the valuable radishes themselves, the leaves of radishes themselves are also a kind of vegetable that can be stir-fried. Or, they can also be used as green feed to feed livestock.
In fact, eating radish leaves is a popular trend among modern talents. In the past, farmers generally disdained to ask for radish leaves and used them to feed them to pigs.
No matter what, whether it is used as vegetables or feeding animals, it is very useful. Moreover, because radishes can be harvested for a season before winter, not only can they be used as vegetables for people, but also can supplement the livestock with fresh green feed. After all, there is no green feed before winter in late autumn. Being able to eat some fresh radish leaves is also a VIP enjoyment for livestock.

Because spring plowing had long passed, Marin asked Angela to gather a large number of serfs in the name of the North Sea Mission to reclaim wasteland, or to find open spaces in the manor under the name of the Hoffman family, and plant radishes and cabbage.
In fact, cabbage, like radish, grows fast and produces high. The growth cycle of cabbage is about two months, and the yield per mu is several thousand kilograms. Even in this era, there is no problem with yield per mu of two or three thousand kilograms.
Marin didn't know how shocking the radish and cabbage he introduced in 16th-century Europe, which yielded only about 100 kilograms per mu, brought to the European rust...
Later, the Beihai Kingdom and later England competed to grow Chinese varieties of radish and cabbage. These two types of vegetables also became the main vegetables in the Beihai Kingdom and the United Kingdom.
Moreover, there was a joke circulating in Germany and England - an uncle named John walked into a small restaurant and shouted "Mary, serve sauerkraut!", and then shouted "Another dish of dried radish, it's spicy!"
Then, later Southern Europeans, when they swear in England and northern Germany, would say—“Hey, those Yankees who grew up eating sauerkraut and dried radish”…
Hundreds of years later, Germany's most classic delicacies were not sausages, but sauerkraut and dried radish. People from northern China felt very friendly when they traveled to Germany and almost thought they had returned to their hometown...
...
In addition to a lot of radish and cabbage seeds, Malin actually brought a lot of ready-made dried radish and sauerkraut. As for fresh radish and cabbage, Malin didn't. Because he had to sail through the tropical areas, fresh radish and cabbage could not be preserved. So he could only bring some seeds back. As for the finished product, he only brought a few jars of pickled sauerkraut said to be pickled sauerkraut from old jars, and there were a lot of salted radishes.
However, these salted radishes are not very delicious because they don’t have chili peppers (there were no chili peppers before the Ming Dynasty). But sauerkraut is very popular with Marin because when cooking, Marin can add some chili and ginger.
Because hiding in the secret house was boring, when Marin was fine, he called Kohler, Schwartz and others, and he and Kahn, cooked a pot of pickled fish in the house, made some grilled skewers, and brought a bucket of dark beer. While eating pickled fish, pickled skewers, and drank skewers, don't feel too good. However, because they were all gathered together to eat pickled fish, pickled skewers and drink beer at night, Marin obviously felt that her belly was getting bigger these days - obviously, this way of eating and drinking is too easy to gain weight...
As a last resort, after eating and drinking with Kohler and others every day, Marin did not dare to sleep immediately, but ran around the big yard of the house to consume energy. Otherwise, the general's belly would come out.
The sauerkraut fish he "invented" quickly became popular in Beihai Country. First of all, after Kohler, Schwartz and others had eaten sauerkraut fish, they walked away from Marin and cooked it themselves.
Later, sauerkraut fish became a famous German dish, comparable to French truffles and foie gras. Then, this method was passed back to China and became a famous dish in the town of Western restaurants...
Many ABCs who are wearing fashion will snap their fingers when they enter Western restaurants and shout:
"Waiter, give me a German-style pickled cabbage fish! It will take 82 years to pickled cabbage (will you eat it dead?)..."
