This is about a recent study looking at the rheology of fondant. Essentially, fondant is created from a supersaturated solution of sucrose that is agitated (kneaded). This causes the fondant to experience a sequence of events:
- First, the agitation induces crystal nucleation and growth. In the early stages of crystal formation, the surrounding solution is depleted of sucrose, reducing the bulk viscosity.
- However, as the crystals grow in size, they are large enough to push against one another in hard sphere-like interactions. This causes a sharp increase in viscosity at this critical crystal size.
- As agitation continues, sucrose crystals fracture and the system reaches an equilibrium crystal size distribution, causing the viscosity to decrease from its peak. This is the final state of a smooth, pliable fondant.
There is a doi provided by the article, but as of my posting this, the doi hasn’t been activated yet.

We need a comparable r/fondanthate haha. I am surprised number 4 wasn’t that they found that fondant is it’s own state of matter. ;) Strange material.
