Although the technology of ancient people is, in most cases, not as advanced as that of modern people today, the gap between them in terms of diet is not as large as the gap between their technology.
This is especially true for the food of the ancient royal aristocracy. At least for most modern people, except for very few foods with too much distinctive taste, almost all high-end ancient foods taste good.
At least Leonard Ethan's current batch of cheese he is selling is such. After the guests received those cheeses and tasted them, the feedback from most people was very positive.
Compared with the industrial-produced cheese, these traditional royal cheeses have a richer taste and can bring more delicious tastes to diners in cooking.
In addition to selling, he also packed the first batch of samples and sent them to his friends and acquaintances, even those he had only met briefly.
