Mamono Realm Shellfish and Slime Jelly Terrine is a dish described in detail in Monster Girl Encyclopedia World Guide - Side II book.
Book Entry
Among the dishes served at Salvarision Castle, I primarily recommend that you try this one. The slimes that produce this jelly dwell in Lake Salvarision, which surrounds the castle and is filled with the powerful mamono mana of the dark knights. Thus, these monsters grow and live in an environment filled with many magical components, so their slime is thickened and coated with a hard shell. If you crack it and taste even a small piece of this jelly, you will feel the thick, rich taste of these components along with the pleasant refreshing notes.
The bulk of the jelly of these slimes is inside a shell of hardened jelly, where the mana that is in the water accumulates. It is called "Knight's Armor" in Salvarision because the shell, like armor, also collects mana inside itself and protects the slime itself. If any enemy from outside comes to the shore of this lake, the mana accumulated in the shell can be splashed by the slimes together with the water to the outside. Then, just as in the case of the mamono who bathed in the lake and were washed by the water of this "water cannon," his own shyness will be "broken like a shell" and his hidden desires will be released. If there is a person for whom the one who has been doused with this water has feelings, the one doused will immediately express his true desires, which he used to hide.
These properties are effectively inherited by this solid jelly, even if it is cut into pieces for serving. Even an initially awkward mamono and human couple will become less tense while eating this dish, and by the end of the meal will be able to confess their love to their partner. Eventually the couple, holding hands, will head to bed to deepen their mutual love.[1]
