Vegetable Mock Crab 素蟹粉
Vegetable Mock Crab is featured among the local specialties of Shanghai.
Su xiefen (素蟹粉) is a vegetable preparation designed to evoke crab meat and roe. A documented version uses potato, carrot and mushrooms to create the contrasting colours and soft texture of the finished dish.
How it is prepared
In the reviewed home recipe, the vegetables are cooked and mashed, combined with chopped mushrooms, then briefly stir-fried with ginger and seasoning. Vinegar supplies a sharp finish associated with eating crab, without making crab an ingredient in that example.
Flavour & texture
The potato gives body, carrot contributes colour and the ginger-vinegar seasoning shapes the resemblance. Its soft texture differs from intact vegetable pieces and from a plate of actual picked crab meat.
Local context & naming
Mock crab describes the intended texture and appearance, rather than a fixed list of ingredients. The linked potato-and-carrot recipe is one example; a restaurant may use a different combination, so confirm its actual ingredients.
Ordering this dish
Ask what substitutes the kitchen uses and whether its stock or sauces contain seafood. If you want a strictly plant-based meal, also confirm egg, dairy and animal fat rather than relying solely on the word su.
At the table
Try a small spoonful before adding vinegar, because the kitchen may already have balanced the acidity. Plain rice can provide a neutral accompaniment when tasting the soft, strongly seasoned mixture.
Ingredients to check
The documented version uses vegetables, mushrooms and seasonings. Check egg, seafood sauces and other additions in any alternative recipe.

Shanghai Rice with Greens 菜饭 →
Shanghai caifan (菜饭) combines rice with chopped greens. Many versions also contain cured pork or ham, and some use meat stock, so its literal name of vegetable rice does not establish a vegetarian meal.
Alfalfa Greens with Pork Intestines 草头圈子 →
Caotou quanzi (草头圈子) pairs alfalfa greens with pork large intestines. The name hides an important ingredient: quanzi refers to the rings of intestine, so this is not simply a plate of green vegetables.
Questions before you order
Does mock crab contain crab?
The reviewed vegetable recipe does not. Other kitchens still need to confirm their complete ingredient list.
