Actually, it’s just a matter of adding your favorite ingredients to various hot pot ingredients. The sweetness is mainly from vegetables, the sourness is from vinegar, the spiciness is from pepper, and some chili pepper and Sichuan pepper powder are all available in supermarkets. But it’s better to buy it at the market. If you have more ingredients, you can choose more and cook them. The thicker texture is just sweet potato powder mixed with water.
