Help translating 块子 and 还看到了小时候才看到“块子”
块子
There are two possibilities, 炒面块子 and 大酱块子.

炒面块子  

用炒过的糠粃，加在煮熟的红薯里捣烂和匀，压成块状晒干制成的食品。常为北方穷人家过冬的粮食。


The bran/chaff (糠 kāng) and unripe grains (粃=秕 bǐ) are stir-fried.  
The red sweet potatoes are cooked and smashed.  
Mix together evenly and then press into blocks (块子).  
Insolate.  


It is often the winter food for the northern poor people.



东北大酱

(November/December) The soybeans are cooked with water for two to three hours.
Crush and make into blocks (大酱块子).
Wrap with paper.
Ferment.

(May) Clean the surfaces with brush.
Cut into small pieces and put them in a big container.
Add water and salt.
Cover with cloth.
Ferment.
Stir every day for more than a month.

BTW
Korea has the doenjang (韩国大酱).
Japan has the miso (味噌).
They are all made out of the soybeans, the paste and fermentation.
