Asparagus is one of the most nutritionally well-balanced vegetables, which is high in "folic acid/叶酸" and is a good source of "potassium/钾, fiber/纤维, vitamin B6, vitamins A and C, and thiamin硫胺素维生素/B1". Moreover, asparagus has no fat, no cholesterol and is quite low in calories and sodium. It is very popular in Europe, especially Germany where promotions, creative events, and festivals are held to honour the arrival of what's crowned as "Königliches Gemüse" - royal vegetable. There's even an asparagus peeling competition/Spargelschäl-Wettbewerb during the celebrated asparagus season, and the crowning of an asparagus king or queen. Along with the asparagus-based delicacies, a range of German white wines, such as Riesling, Müller-Thurgau or Grauburgunder, together with some interesting reds, will be launched. White asparagus are sunlight-deprived stalks and they are milder and more delicate than the green one.
- Before start cooking white asparagus, they must be peeled, as the outside is fibrous and even woody at times. Use a common but sharp vegetable peeler, starting just below asparagus spears, peel toward the cut end. Once all the asparagus has been peeled, cut off the cut ends about one inch up. Slice the tomato into wedges and the spring onions into smaller chunks.
- Heat up a skillet over medium-high fire. Stir in XO sauce and minced garlic until aromatic. Add in the prepared white asparagus, stir briefly, drizzle water and white wine over. Cook until soft to your liking. Add in tomato wedges and spring onions. Mix everything together. Flavour with salt and serve.
