What should be done to fries after initially salting them?

After initially salting fries, it is essential to salt them again to ensure that the seasoning is properly absorbed and evenly distributed. This process enhances the flavor and ensures that every fry has an optimal taste. Salt not only adds flavor but also can help to draw out moisture, maintaining the crispness of the fries.

While letting them cool may seem practical, it doesn't enhance their flavor profile. Serving them immediately without an additional salting might leave some fries under-seasoned, leading to a subpar customer experience. Placing them in the warmer can keep them hot, but it does not address the need for proper seasoning. Thus, the best practice is to season them again after the initial salting to achieve the best flavor before serving.
