When making batters for frying, the type of starch and the amount used will greatly impact the quality of the batter.
In terms of wheat flour, the higher the protein content, the tougher the crust will be because more gluten will be present in the batter. Since gluten absorbs both moisture and fat, the higher the protein content, the chewier and oilier the crust will be (bread flour has 12-16% protein). This is why all-purpose flour, with its moderate protein content (10-12%)is commonly used. The developed gluten helps the batter cling to the food without producing an overly chewy or oily crust. However, if too much flour is used, the batter will produce a very tough crust; and, if too little is used, the crust will be very fragile. For this reason, wheat flour is often combined with other low or no-gluten flours such as cake/pastry flour (7-9%), cornstarch and rice flour to reduce the overall gluten content present in the batter. Rice flour and cornstarch work particularly well because they fry up crispier than wheat flour. They also absorb less moisture and fat during the frying process, making the products less greasy. This is why rice flour is often used when making tempura because it produces a very thin and crispy, dry crust.
The more wheat batters are mixed/whisked, the more gluten will be developed. Many batters are mixed just until they are combined – even if lumps are still present. Other batters are mixed/whisked until completely smooth; however, depending on the ingredients, wheat batters are often left to rest for a period of time in order to let the gluten relax before any food is dipped into it.

How does starch affect batters for frying? ›
During the frying, the starch granules within the batter coating of the chicken nuggets swell, releasing amylose fraction. This amylose fraction then forms a film-like barrier, as previously mentioned, which effectively prevents the penetration of oil and the loss of moisture from the coated food items.
What happens when you fry starch? ›
The hydrated granules swell when they are initially heated in the oil, allowing the starch molecules to move about and separate from one another. As water is driven away during the frying process, these starch molecules lock into place, forming a rigid, brittle network with a porous, open structure.
How does flour affect batter? ›
Research indicated that batters with higher protein content are generally more effective as binding agents. Wheat flour with higher protein levels has been reported to increase batter viscosity and produce darker, crisper fried foods.
Is cornstarch or flour better for frying? ›
Cornstarch typically makes for a crispier finish than flour. Cornstarch absorbs moisture from the food and expands, giving deep-fried foods a crispy coating. When the food is fried, the moisture cooks out of the cornstarch, leaving a crackly, puffy coating on the outside.
Which starch will create the crispiest batter for frying? ›
Rice flour and cornstarch work particularly well because they fry up crispier than wheat flour. They also absorb less moisture and fat during the frying process, making the products less greasy. This is why rice flour is often used when making tempura because it produces a very thin and crispy, dry crust.
What does cornstarch do to batter? ›
Cornstarch not only acts as a thickening agent, but it can also be used in baked goods like cookies, brownies and cakes. If you're searching for more structure in your favorite dessert recipe, then cornstarch might be just the ingredient you need!
How is starch affected by cooking? ›
In general, starch content decreased after cooking. Baking degraded starch by up to 20% and performed similar trend to raw sweetpotatoes.
What happens to starch when cooking? ›
When we apply heat, the starch granules swell and then burst, causing the release of more starch molecules into the liquid; thickening then occurs. You should not add starches directly to hot liquids. The edges of the starch will immediately gelatinize and form lumps.
Does starch make fries crispier? ›
Potatoes contain two types of starch: amylose and amylopectin, each playing a crucial role in the texture of the cooked fries. Amylose starch contributes to the crispy nature of fries by forming a rigid structure during the frying process.
Cornstarch contains a higher percentage of amylose than flour or potato starch. This is what makes cornstarch into a more crispy coating during frying.
How does batter become crispy? ›
Water: Use very cold water for the crispiest results. Baking powder: Baking powder ensures a light and crispy exterior. Salt: A teaspoon of salt enhances the overall flavor of the fish batter.
What is a good quality thick batter for frying? ›
A combination of all-purpose flour, cornstarch, and baking powder yields a batter that's thick enough to coat whatever you dip it in but that fries into a light crisp.
What is a substitute for cornstarch when frying? ›
If you don't have cornstarch, you can substitute all-purpose flour in favor for a more routine breading and frying procedure. You can also use rice flour or potato flour, which are commonly used for tempura, and this will create a similar lacy, crunchy texture.
What happens when you add cornstarch to flour for fried chicken? ›
When paired with all-purpose flour, cornstarch helps prevent gluten development, which makes the flour coating crispier, and absorb moisture (from the frying and the chicken), which also means a crispier coating. If you already have a favorite fried chicken recipe, try replacing a quarter of the flour with cornstarch.
Can you deep fry with cornstarch? ›
Place chicken pieces, one at a time, in the bag, seal and shake to coat. Add more flour and cornstarch as necessary, but add them in equal parts. Heat oil in a deep-fryer or large saucepan to 375 degrees F (190 degrees C). Be sure to use enough oil to cover chicken pieces.

Starch can give your chickens a sticky boost
For every half cup of flour, adding about 2 teaspoons of cornstarch (8% to 10% of the flour's weight) is a great rule of thumb if you're planning on trying this trick. But don't feel like you have to stick to cornstarch! Any type of starch will do.
What does starch do for fried chicken? ›
In a wheat flour-based batter, potato starch and cornstarch perform a similar function. They both inhibit gluten formation, limit oil absorption, and produce a crispier texture.
