1, this kind of cut cake and chestnut cake are actually the same thing, both of which are particularly heavy. Cut a small piece and it is estimated that the weight of the two is equivalent;

This kind of cut cake contains many kinds of dried fruits, such as walnuts, peanuts, sunflower seeds, raisins and dried apricots. In terms of cost, it is actually not cheap. Mainly by sugar bonds;

3. According to the online query, I can't verify it: pour it into a solid wooden trough while it is hot (the wooden trough is surrounded by several separate boards, which are fixed together with thick hemp ropes and big nails bent at both ends), then cover the cake with a board and press some heavy objects, such as stones or iron blocks. In short, it should be heavy enough, and it is understandable to find some chubby people standing on it. In this way, the cake is slowly pressed, and a large amount of water inside slowly flows out with the gap at the bottom of the wooden trough. Two days later, remove the heavy objects or chubby people, pry up the nails, untie the hemp rope, take off the board, and a solid and delicious cake will appear in front of us;

4. This opens a high-density cut cake, just like a compressed biscuit. Just like compressing a hot steamed bun into a small size, the weight of the compressed steamed bun actually estimated by the naked eye is quite different from the actual weight;

This is probably the way, and the workmanship should not be so bad.
