Zesting is a construction of a new braided fusion category from a given braided fusion category by defining a new tensor product.

If $\mathcal{C}=\bigoplus_{a \in A} \mathcal{C}_a$ is an $A$-graded fusion category where $A$ is an abelian group, we define a new tensor product $X_a\stackrel{\lambda}{\otimes} Y_b:=(X_a\,\otimes\, Y_b)\otimes\,\lambda(a,b)$, where $X_a\in\mathcal{C}_a$ and $Y_b\in\mathcal{C}_b$ are simple objects in their corresponding graded components and $ \lambda(a,b)\in\mathcal{C}_e$ is an invertible object in the trivial component.

In this work, I present a total description of the Braided Zestings from the modular category $SU(N)_k$ obtained from the quantum group $U_q (\mathfrak{sl}_n)$ extending the work on [2] by giving explicit calculations for finding of all the braided zestings obtained from $SU(N)_k$. \textbf{ References:} [1] C. {Delaney} and C. {Galindo} and J. {Plavnik} and E. {Rowell} and Q. {Zhang}, \textit{Braided Zestings and Aplications}.
