Common Mistakes to Avoid

Making Kohakutou candy can be fun, but there are some pitfalls to watch out for. Here are common mistakes and how to avoid them.

  • Using the Wrong Agar-Agar: Not all agar-agar powders are created equal. Use a high-quality powder specifically meant for cooking to ensure proper gelling.
  • Ignoring Flavoring Measurements: Too much or too little flavoring can ruin your candy. Stick to the recommended ¼ teaspoon for balanced taste.
  • Skipping the Cooling Step: Allow the mixture to cool before cutting into shapes. Rushing this step can lead to a gummy texture instead of the desired crystal effect.
  • Not Using Food Coloring Wisely: Adding too much food coloring can alter the taste or texture. Start with a few drops and adjust gradually for vivid colors without overpowering flavors.
  • Overcooking the Mixture: Cooking the mixture for too long can affect its final consistency. Keep an eye on it and remove from heat as soon as it thickens.
