bean vermicelli

Bean vermicelli, also known as mung bean vermicelli, glass noodles, or cellophane noodles (粉絲 in Chinese; bún chỉ in Vietnamese), is a thin, translucent pasta made from mung bean starch and water. These noodles originate from East and Southeast Asia, particularly China and Vietnam, and have become foundational across Asian cuisines. The noodles are typically 1-2mm in diameter and range from pale white to slightly translucent when raw. When cooked, they become soft and slippery with a delicate, slightly sweet flavor and a gelatinous texture that readily absorbs surrounding flavors.

The production process involves extracting starch from mung beans, mixing it with water to form a dough, and then extruding or pressing the dough through fine holes to create thin strands. These strands are then dried, which gives them their characteristic brittle, glass-like appearance. Some regional variations include bean vermicelli made from other starches such as tapioca, potato, or sweet potato, though mung bean remains the most common and authentic source.

Bean vermicelli serves as a versatile ingredient across Vietnamese, Chinese, Thai, and broader Southeast Asian cuisines. It is commonly used in spring rolls (both fried and fresh), soups, stir-fries, and cold noodle salads. The noodles are particularly valued for their neutral flavor, which allows them to integrate seamlessly with bold sauces and broths. In Vietnamese cuisine, they feature prominently in dishes like bánh chưng (sticky rice cakes) and various imperial rolls. In Chinese cuisine, they appear in hot pot preparations and braised dishes. The noodles require minimal cooking—typically just a brief soak in hot water or quick boil—making them convenient for quick preparations and cold dishes where they're tossed with vegetables, herbs, and dipping sauces.
