In more advanced culinary contexts, "thạch" can refer to various types of jellies or gels used in cooking and baking. Chefs might use "thạch" to describe different techniques for creating textures in desserts, such as layering different colored or flavored jellies.
While "thạch" primarily refers to gelatin or jelly, it can also be used metaphorically to describe something that is solid but has a soft or wobbly texture.
In Vietnamese culture, "thạch" is enjoyed in various forms, especially during hot weather. It's common to see colorful layers of "thạch" in dessert shops, making it a visually appealing treat as well.
