prepare the ingredients
cook the potatoes in boiling salted water for 15-20 mins
mix all the sauce to creamy
chopped potatoes into chunks
Stir together, add the tarragon and nuts on top
1. 嫌麻烦如我其实没全按着recipe来~例如walnut我换成cashews 没放walnut oil会稍欠香气但还是可以用同等分量olive oil替代 2.同理没有fresh tarragon可以用干货代替,不然chopped parsley其实也很有herb的香气
