有2000多年土豆种植史的南美洲秘鲁-Peru是土豆-"Earth Bean" (又名马铃薯-"Horse Bell Yam")的真正故乡。 Funny thing is in my hometown 土豆-Earth Bean is not potota, but peanut. 德国人管土豆叫Edrapfel (Ground Apple in English)or Kartoffel, 是世界上吃土豆最多的民族，每人平均每年吃掉七十公斤土豆。

Potato Varieties-Kartoffel Sorten
平常我一般是不吃土豆的，不过上星期公婆来访，所以在ALDI超市买了1kg/一包,好像是1，5欧左右，用了一半做Salzkartoffeln mit Petersilie/盐水欧芹土豆，还剩一半就用来做这个沙拉了。

1. 
   Boil the potatoes in salted water until they are just soft. Drain and peel off the skin. Whisk together freshly squeezed lemon juice, mustard, pepper and salt in a bowl until the mixture is well blended, then start to slowly beat in the olive oil. Add in the spring onions.
   土豆放到盐水里煮软后滤干后剥掉表皮备用。柠檬汁，芥末，胡椒和盐打匀后徐徐加入橄榄油搅打至完全混合。拌入葱花。
   
2. 
   Dry fry the ham cubes over a low heat for 5 minutes and add the ham to the dressing. Thickly slice the warm potatoes and add to a serving bowl, then pour over the dressing. Toss to mix through then sprinkle over with the chopped parsley before serving.
   将熏肉丁入锅低火干炒5分钟后倒入调味汁里拌匀。将土豆切成后片放到大碗里，倒入调味汁。兜匀后洒上欧芹末即可食用。
