作法
- 煉乳舀入高玻璃杯底。份量是個人偏好：2大匙較不甜，4大匙是西貢街攤的全甜。
- Phin濾杯放在小碗或杯上（先別放在玻璃杯上）。加入咖啡粉抹平，再放上壓盤（重力壓器）——別鎖緊。
- 倒20毫升沸水在咖啡粉上。等30秒讓粉膨脹——這是悶蒸步驟。預濕能讓萃取均勻。
- 倒入剩餘100毫升沸水。蓋上phin蓋。水應慢慢透過咖啡粉滴出——適當鎖緊的phin每分鐘50–80滴，4–5分鐘完成。太快旋緊壓盤；太慢放鬆。
- 滴完後把phin拿開，把熱咖啡直接倒在煉乳上。用長湯匙用力攪拌30秒；混合物應變均勻奶油焦糖色，看不到白條紋。
- 把冰塊加到杯中至滿。熱咖啡奶倒在冰上幾乎瞬間冷卻。用長湯匙攪一下。配長湯匙與吸管上桌。

This recipe is written for 1 servings. To scale, multiply each ingredient proportionally; the cooking times stay the same up to about double the volume. Beyond that, expect to cook in batches because of pan size and heat distribution.
文化背景
Ca phe sua da是西貢早晨——人行道塑膠凳、phin平衡在小玻璃杯上、慢滴與更慢的對話。羅布斯塔豆是越南招牌；阿拉比卡有時混合但深沉、略苦、近乎可可豐厚的風味來自羅布斯塔，它能適應越南氣候而阿拉比卡不能。煉乳是第二個法殖民遺留（在長棍麵包之後）——二十世紀初越南鮮乳罕見，罐裝甜煉乳是必備品；這個組合就此留下。
