Before diving into making sesame balls, gather all your ingredients. Ensure your work area is clean and that you have a deep fryer or pot ready to go. This makes the cooking process smoother and more enjoyable.

In a mixing bowl, combine glutinous rice flour, granulated sugar, and ground cardamom (if using). Mix well. Gradually add water and one teaspoon of oil, mixing until a soft dough forms. You want a texture that is pliable but not sticky. If it's too dry, add a little more water.

Divide the dough into equal portions, about the size of golf balls. If you're using a filling, flatten each ball slightly, place a small amount of red bean paste in the center, and fold the edges over to seal. Roll them gently in your palms to smooth out any imperfections.

Take each ball and roll it in a shallow plate of toasted sesame seeds until fully coated. Make sure to press gently so that the seeds stick. This will create that desirable crunch!

In a deep pot, heat the neutral oil until hot but not smoking. To test the temperature, drop a small piece of dough into the oil. If it rises to the surface, you’re ready to fry.

Carefully place a few balls into the hot oil. Do not overcrowd the pot. Fry them for about 5–7 minutes, turning occasionally until they are golden brown on all sides. Use a slotted spoon to remove the balls from the oil and let them drain on paper towels.

Let the sesame balls cool for a couple of minutes, then serve them warm. Be prepared for compliments. The bites are a delightful mix of textures that will captivate everyone.
