The canned food was a patent invented by a French chef who discovered that food sealed in glass containers was not perishable if it was properly heated.
Coincidentally, Napoleon was troubled that his soldiers could not eat fresh fruits and vegetables. After the food in the can was heated up, being stored in a sealed environment allowed it to have a maximum shelf life of a few years, so it was popularized.
Crab was a good ingredient. Be it crab roe, crab meat, or crab sauce, they were all enthusiastically sought after in the modern market.
If it was made into canned food, not only could it be sold for a good price, but it would also make the world exclaim at the craftsmanship and storage time of the canned food.
The craftsman had the technology to make glass. According to Bai Wutong's request, he quickly made more than 10 glass jars of different sizes.
