Their tofu-making skills had improved greatly from before, and now a pound of soybeans could produce four pounds of tofu.
This morning, they sold 800 pounds of tofu, made from only 200 pounds of soybeans, with an investment of 600 copper coins.
That is to say, just from tofu alone, they made a clear profit of over seven taels.
Then there were the spices. The most expensive ingredient was thirty cents per pound, and the cheapest was fifteen cents. On average, the cost for a pound of spices was a hundred copper coins.
A pound of spices could make a hundred packets, selling at five copper coins each, making five hundred copper coins per pound, netting a profit of four hundred copper coins.
Today, their 800 packets of spices earned them three taels and two hundred copper coins.
The total profit from both items was more than ten taels.
Even Third Grandpa, who had lived a lifetime and experienced many things, couldn't help but get excited.
