"the essence of the method" is a grammatically correct phrase and can be used in written English.
It refers to the most important or fundamental aspect of a method or approach. Example: "In order to fully understand the concept, one must grasp the essence of the method being used."
The essence of the method is to cut the spectrum into slices over the frequencies at the selected wavenumbers.

The essence of the method involves the use of a coarse grid discrete representation of the model differential equations (in both time and space) and parameter estimation.
The essence of the method of the solution-spectral relaxation method SRM is to linearize and decouple the original system of PDEs to form a sequence of independent linear equations that can be solved iteratively.
The essence of the method is the partitioning of P into a main Pm and an intermediate Pi serving as buffer, with concomitant definition of two types of wave and excitation operators.
The essence of the method is to introduce the modulated coordinates such that the periodically time-varying linear differential equations can be effectively transformed to the equivalent time-invariant linear differential equations.
We discuss here the essence of the methods now available to cover a wide range of structure and properties.
While obviously much larger temperature steps are used for the T-history method and the power is determined by a differential approach, the essence of the methods is the same.
