Waterlogged

I feel like I come across the term “waterlogged” often enough, but never seem to get an explanation of it.

In short: Waterlogged is the over-absorption of water into the cells of a vegetable due to the degradation of the water absorption control of cell walls via a cooking process.

The common scenario is something like the instructions for cooking green beans:

1. Blanch them for a short period of time to both cook them and bring out the color

2. Shock them in ice water to dramatically reduce the cooking process

3. Remove and let dry to prevent becoming waterlogged

I find this a bit frustrating and unsatisfying that it is always assumed that the reader knows what this is.

Cooking a vegetable typically means a chemical process changes the structure of that vegetable. A very common occurrence is that the cell walls are ruptured or degrade, and the vegetable is hydrated. If this happens too much, the vegetable will have a soggy texture, not something more crips. Moreover, a lot of flavor is lost and muted through diffusion and osmosis.

Leaving a vegetable in water for too long, especially after or during cooking, will result in what is commonly described as “waterlogged” - a bloated, soggy result.

Salting water can help slow the process of waterlogging by pulling water out of the ingredient to balance the salt concentration via osmosis.
