剛購入了Rocket R58
蒸氣很足,也很夠力,但是怎麼打也打不起來,
不是消泡就是直接煮滾,
一直以為是自己技術太爛或是機器有問題,
直到職業的友人來訪,一打......奶有脹了,但是蒸好後立刻消泡...當場傻眼.
後來朋友再拿一瓶奶,再打一次,這次就更慘了.連脹也沒有,只是把奶溫熱而已.
朋友教我用沙拉脫加水練習法,一下就打得好好的,
後來我們推論是牛奶有問題,
今天我上網找了些資料來看,發現了一件事,
奶泡在乳脂肪5%時,穩定度最差.
奶泡的綿密度:乳脂肪愈高,綿密度愈佳.
奶泡的生成量:在乳脂5%以下時,乳脂愈高,奶泡量愈低.
奶泡的穩定度:在乳脂5%以下時,乳脂愈高,穩定愈差.
我查了我平時喝的鮮奶的乳脂量,很不幸的,是5.2%.
難怪怎麼打也打不起來.
今天中午去COSTCO補了一桶林鳳營,很順利地.一打就好,奶的表面也很亮.
所以,奶好不好打,跟乳脂含量關係很大.
跟大家分享一下,今天的心得.
