You follow the same recipe step by step, yet the dessert turns out denser, runnier, or less crisp than before. Even a small change in the type, brand, or proportion of flour can alter the texture because different flours absorb water, cook, and build structure in different ways. This article starts with the problem you can actually see, then works backwards to identify what changed—whether it was the flour, liquid, heat, or process—so the recipe can be corrected at the right point.

5 Common Problems Caused by an Unsuitable Flour Choice

.

.

1. Dense, Heavy Texture That Firms Up After Resting — Common in Steamed Banana Cake

Steamed banana cake should be moist, soft, and able to hold its shape. However, the ripeness of the bananas can vary from one batch to another. Very ripe bananas usually contain more moisture, while less ripe bananas may produce a drier texture.

If there is too much flour for the available moisture, or if the chosen flour creates a fairly firm structure, the dessert may become heavy and grow even firmer as it cools.

 .

Before increasing or reducing the flour, check whether:

• The bananas are as ripe and moist as those used in the previous batch
• The amount of coconut milk or water has changed
• The same mould size was used
• The dessert was steamed for too long or over excessively high heat

Wet-milled rice flour or jasmine rice flour can help the dessert hold its shape, but the proportion must match the bananas and other liquids. Do not add more flour immediately simply because the mixture looks runnier than before.

2. The Topping Does Not Set or Releases Water — Common in Khanom Thuai

The coconut topping on khanom thuai should be smooth, soft, and stable enough to scoop. If it remains runny or releases water, the flour may not provide enough thickening power. However, the cause could also be coconut milk with a high water content, insufficient heat, or condensation dripping from the steamer lid onto the dessert.

Conversely, too much flour can make the coconut topping firm and take away its delicate texture.

Cornstarch, tapioca starch, or arrowroot starch may improve thickness and stability in certain recipes, but adjust the amount gradually and check the steaming method at the same time. Otherwise, flour may be added repeatedly even though the real problem lies in the heat or liquid content.

3. The Dough Is Hard, Crumbly, or Cracks While Shaping — Common in Khanom Tom

Khanom tom requires dough that is soft, chewy, and elastic enough to wrap around the filling. If the dough is hard or cracks while being shaped, there may be too little water or the flour may not yet have absorbed the water fully.

If the dough is so soft that it loses its shape, too much water may have been added or the chosen flour may not provide enough elasticity.

 

Glutinous rice flour plays the main role in creating chewiness, but achieving the right texture also depends on:

• The temperature of the water used for mixing
• The amount of water
• Kneading and resting time
• Boiling time
• How the dessert is rested after cooking

 

When adding colour and aroma with black glutinous rice flour, begin by combining a small amount with the main flour. Changing the proportion too much at once can alter the aroma, colour, and texture simultaneously.

 

4. Not Crisp, Too Oily, or the Coating Falls Off — Common in Fried Bananas

The crispness of fried bananas does not come from flour alone. It depends on the balance between the flour mixture, the moisture in the bananas, and the oil temperature.

If the batter is too thin, the coating may be weak and fall off easily. If it is too thick, the crust may become heavy, hard, or unevenly cooked. Frying in oil that is not hot enough will also cause the dessert to absorb more oil.

 

Before changing the recipe, check whether:

• The batter coats the bananas evenly
• The bananas are releasing more moisture than usual
• The oil is hot enough before the bananas are added
• Too many pieces are being fried at once, causing the oil temperature to drop

 

Rice flour, tapioca starch, and cornstarch can be combined to adjust crispness. However, change only one type or proportion of flour in each test batch so you can identify what genuinely affects the result.

 

5. Attractive Colour but an Overly Dense Texture — Common When Using Coloured Rice Flour

Riceberry rice flour, black glutinous rice flour, and yellow jasmine brown rice flour add the natural colour and aroma of rice, but they affect more than the appearance of a dessert.

At higher proportions, the rice aroma may become stronger, the colour may deepen, and the texture may become denser or heavier depending on the properties of each flour.

A more controllable approach is to begin by blending coloured rice flour with the main flour, then increase the proportion gradually while observing the colour, aroma, texture, and changes after the dessert rests.

 

The Same Symptom Does Not Always Mean Flour Is the Cause

Changing flour may be one possible cause, but the symptom alone is not enough to reach a conclusion. Many dessert problems can also come from other factors.

 

• A hard dessert may result from too much flour, too little liquid, or excessive heating time.
• A dessert that does not set may result from unsuitable flour, insufficient heat, or too much liquid.
• A crumbly dessert may result from too little water, uneven kneading, or insufficient resting time.
• An oily fried dessert may result from oil that is not hot enough or from frying too much at once.
• An uneven texture may result from inaccurate weighing or incomplete mixing.

Finding the cause therefore means reviewing the recipe, ingredients, and process together—not simply increasing or reducing flour based on instinct.

 

How to Test a Flour Change Without Losing the Whole Recipe

 

Define the Texture You Want First

State clearly whether the dessert should be soft, chewy, thick, stable, or crisp. A clear goal makes it easier to select the flour and evaluate the result.

Check the Role of the Original Flour

A recipe may use several flours because each performs a different function. One may build structure, another may add chewiness, and another may increase thickness. Before removing any flour, identify what will replace its original role.

Change Only One Factor per Test

Change either the type or proportion of flour first while keeping the water, heat, and other steps as close to the original as possible. If everything changes at once, even an improved result will not reveal the true cause.

Test a Small Batch

Dividing the recipe into small test batches reduces waste and makes results easier to compare, especially when the recipe uses many ingredients or involves a lengthy process.

Record the Results Immediately and Again After Resting

Some recipes may look good while hot but become firm or release water after resting. Checking the dessert after it cools is therefore just as important as checking it straight from the kitchen. Record:

• The type and quantity of flour
• The amount of water, coconut milk, or other liquid
• The heat level and cooking time
• The texture immediately after cooking
• The texture after cooling or after the specified storage period

.

Choose Flour Based on the Result You Need

Once you understand the role of flour in the recipe, choosing an ingredient no longer depends only on its name or familiarity.

• For a dessert that should hold its shape while staying soft, start by considering rice flour.
• For chewiness and elasticity, glutinous rice flour may be the main component.
• For added thickness or binding, cornstarch or tapioca starch may be used as supporting ingredients.
• For natural rice colour and aroma, coloured rice flour may be combined with the main flour.
• For greater stability or a soft, chewy texture in certain recipes, test arrowroot starch in an appropriate proportion.

 .

Fancy Carp Brand offers several groups of flour suited to different dessert characteristics. Choosing flour according to its function in the recipe and the intended texture helps each type perform more precisely than selecting it by product name alone.

 .

When the same recipe no longer produces the same result, it does not mean valuable ingredients must be discarded. Work backwards through what changed—from the type of flour and ingredient proportions to the heat. Bringing a dessert closer to the intended result begins with finding the point of change, then using experience to learn from every mistake.
