Discussion Overview

The discussion revolves around the differences between dry and liquid breadings used in frying food, particularly focusing on fried chicken and fried fish. Participants explore the reasons behind the preference for each type of breading, considering factors such as adhesion, crunchiness, cooking times, and the effects of cooking at high elevations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants note that dry breading is commonly used for fried chicken, while liquid breading is preferred for fried fish, suggesting a possible rationale beyond tradition.
  • One participant identifies two main issues affecting breading: adhesion and desired crunchiness, mentioning that chicken and catfish often use dry crumbs after soaking in buttermilk, while calamari may only require wheat flour.
  • Another participant highlights the challenges of achieving consistent results, particularly with onion rings, and expresses a desire to explore this topic further.
  • One participant points out that high elevation can affect the reliability of frying recipes, particularly those relying on steam, due to changes in boiling point and cooking conditions.
  • Another participant discusses the impact of cooking time and insulation provided by wet batter, noting that a wet batter can protect delicate fish during frying.

Areas of Agreement / Disagreement

Participants express various viewpoints on the effectiveness of dry versus liquid breadings, with no consensus reached on the best approach or the reasons for the observed patterns in recipes.

Contextual Notes

Participants mention the influence of cooking conditions, such as elevation, on frying techniques and outcomes, indicating that these factors may complicate the application of standard recipes.

TL;DR
Are dry breadings generally better on some foods than on others?
Most recipes I see on the internet for fried chicken advocate a dry breading. By contrast, most recipes for fried fish use a liquid breading, although they sometimes specify a preliminary coating with flour before the fish is dipped in the liquid breading. Are there reasons for this pattern - other than tradition?

Now this is an important question. I am still searching for reliable rules of thumb. In my experience the issues can be distilled to two: (1)adhesion and (2) amount of crunch desired.

Chicken and catfish are often done in various dry crumbs but usually after a soak in buttermilk. Calamari just wants wheat flour alone. Then there is tempura which is actually a very simple batter on a variety of stuff. And there are batters which contain egg for the less delicate. And sometimes an egg-wash !

I admit to not getting predictable results. In my experience the most difficult thing to get just right is the perfect onion ring. I intend to pursue this question so long as there is oil to heat...

I think @Stephen Tashi lives at an elevation over 3500 feet. This reduces the reliability of most recipes that rely on steam -- deep frying is one of them. The BP of ##H_2O## is ~95.5°C (204°F). This affects cooking times, temperatures for oil, required starting moisture content, and patience for failure. Baking is a real PITA at high elevation until you get the hang of it. Had at house at 9300 feet. :oldgrumpy:

So I can empathize...

1. Cooking time. Deep fry a wet fish batter for long enough to cook chicken and it will be rock hard (British readers excuse the pun).
2. Insulation. A wet batter creates an insulating layer as the water turns to steam, protecting the delicate fish inside. Catfish is less delicate than fish that are traditionally fried in batter such as cod.
