What is banana oil?
- As a familiar ingredient in making desserts, banana oil is an organic compound based on ester.
- Banana oil is in liquid form, insoluble in water, but soluble in most other organic solvents.
- Banana oil can be formed by distillation, extraction from banana plants or honey, or can be produced in large quantities industrially through acid-catalyzed reactions between isoamyl alcohol and acetic acid.
- In particular, banana oil has a scent similar to ripe bananas, so it is often used to flavor desserts, jellies, cakes, and more.

Prepare the ingredients
For the tapioca pearls and sweet potato flour, pour enough water into two bowls containing the flour to soak for about 30 minutes until the flour softens and expands, then drain the water.
Peel the bananas, cut them into 4 pieces, then marinate the bananas with 2 tablespoons of sugar, 1/3 tablespoon of salt, mix well, and let them soak for about 30 minutes for the bananas to absorb the sugar evenly.
Trim the ends of the sweet potatoes, use a peeler to remove the skin. Then wash the sweet potatoes with diluted salt water, and then rinse with clean water to drain.
Next, cut the sweet potatoes into bite-sized pieces. Avoid cutting the sweet potatoes too small to prevent them from breaking apart when simmering.

Simmer the bananas and sweet potatoes
Place a pot on the stove, add the bananas that have been marinated with sugar along with 300ml of coconut milk into the pot. Heat on medium until you see the coconut milk in the pot starting to boil, then add the sweet potatoes and stir well.
Next, add about 1 liter of water to the pot, cover it, and simmer the bananas and sweet potatoes on low heat for 20 – 30 minutes until the bananas and sweet potatoes are soft and cooked through.
-
Add sweet potato starch and coconut milk
Once you have cooked the bananas and sweet potatoes, add 50g of soaked sweet potato starch to the pot, boil until the starch is cooked and turns translucent, indicating it is done.
Next, add 50g of soaked tapioca starch to the pot and also boil until the starch begins to turn translucent, then season with sugar to taste according to your family’s preference.
Finally, add 100ml of coconut milk, stirring gently. Cook until the coconut milk starts to boil, then turn off the heat.
Note: You should add the coconut milk last and avoid cooking for too long, as this can cause the coconut milk to form a skin when cooled and lose its creamy flavor.
-
Completion
While the dessert is still warm, add about 2ml (approximately 2 drops) of vanilla extract or banana oil to the pot, stirring gently to enhance the aroma of the dish.
Then scoop the dessert into a bowl, crush some roasted peanuts and sprinkle them on top, and you can enjoy it.

How to choose delicious cassava
- When buying cassava, you should choose tubers that are elongated in shape, feel plump and moist when held, as they will be less fibrous, softer, and sweeter when eaten.
- Additionally, when selecting, you should choose tubers that have an intact appearance, of moderate size, not too large nor too small. This is because overly large tubers often contain more fibers and don’t taste good, while small tubers do not have enough starch and do not have a rich flavor.
- Avoid buying tubers that, when you scratch the skin with your hand, reveal a white color, as these tubers are toxic. Non-toxic tubers will have a pink color.

How to choose good bananas for dessert
- Bananas for dessert should be ripe and soft, as they will not be bitter, and the bananas will remain chewy without getting mushy.
- It is advisable to choose a bunch of bananas that are not uniformly colored (some yellow, some green) and have dark or deep pink spots.
- Naturally ripened bananas will have a yellow stem and body. If the stem is green but the fruit is uniformly yellow, it has certainly been treated with chemicals.
- Tree-ripened bananas will have a fragrant smell and natural sweetness, and will be evenly soft. On the other hand, chemically treated bananas will be slightly crunchy, hard, and have a bitter and sour taste.
- Avoid choosing evenly ripe bananas with a deep yellow skin.
How to choose delicious yellow and purple sweet potatoes
How to choose yellow sweet potatoes
- Choose tubers that are round or elongated, without any waist or dents, and if you squeeze them lightly and they are not too hard, these are the ones that are less fibrous, starchy, and taste very sweet.
- Tubers that often have a layer of powder or dirt on them are the fragrant sweet potatoes; when you cut a thin slice at the end of the tuber, you will see a light orange color and sap flowing out, which will taste very good and sweet.
- Avoid buying tubers that are bruised, rotten, or have sprouted.
How to choose purple sweet potatoes
- You should choose medium-sized tubers, as larger tubers will have less starch and be less sweet than medium-sized ones.
- Similar to yellow sweet potatoes, those that still have a layer of powder or dirt on them are new sweet potatoes, which will be starchy and sweet.
- Absolutely do not buy tubers with black spots on the skin. This is a sign that the tuber is spoiled. You should also avoid choosing sprouted tubers as they may have been harvested a long time ago.
What is sago flour? Where to buy sago flour?
