做法:
| 1. | 烤盤上刷些水後鋪上烘培紙。 |
| 2. | 把蛋白放進一個乾淨未沾到油脂或水的盆裡，用中低速打成泡沫狀，加入檸檬汁繼續用高速打成軟性發泡。再慢慢加入1/4杯糖打成硬性發泡。打好的蛋白霜放進冰箱冷藏。 |
| 3. | 將麵粉，鹽和泡打粉一起過篩到碗裡。咖啡粉用1大匙滾水拌勻。烤箱預熱到335°F(170°C)。 |
| 4. | 在一小碗裡將蛋黃和糖先用高速打到開始變白後依序倒入咖啡，香草精和蔬菜油繼續打到充分混合。最後分兩批交替加入粉類和牛奶用中低速打到沒有麵粉粉粒，大約1分鐘。 |
| 5. | 舀1/3蛋白霜進蛋黃麵糊用橡皮刀拌勻。再將蛋黃麵糊倒進蛋白糊盆裡，從盆邊由下往上輕輕翻拌直到蛋白霜与蛋黃麵糊充分混合。切忌過度攪拌。把蛋糕糊倒入烤盤後用刮刀抹平表面。將模具在檯面上敲幾下敲出氣泡。 |
| 6. | 蛋糕糊放進烤箱中層烤約20分鐘，或烤到插入牙籤拔出後牙籤上未沾有麵糊。 |
| 7. | 取出烤盤。將蛋糕倒扣到另一張烘培紙上，慢慢掀開墊底的烘培紙。用刀在短向的一邊劃三道(間隔2.5公分)，但不要切斷。然後抹上 打發鮮奶油 , 底端留3公分長條不要塗。 |
| 8. | 將蛋糕從短向捲起，開始捲時要收緊不要有空洞。捲完用保潔膜包住放定型，再進冰箱冷藏至少2個小時後再食用。 |
PROCEDURE:
| 1. | Brush the base of the baking pan with little water then cover with a piece of baking parchment paper. |
| 2. | Place the egg whites in a clean bowl and whisk in medium-low speed until foamy. Add the lemon juice and continue to beat in high speed until soft peaks form. Gradually add the sugar and beat in high speed until stiff peaks form. Store the meringue in the fridge. |
| 3. | Sift the flour, salt and baking powder together into a bowl. Dissolve the coffee powder with a tbs. of boiling water. Preheat the oven to 335°F(170°C). |
| 4. | Beat the egg yolks and 3 tbs. of sugar in a small bowl until the mixture starts to turn white. With the mixer running, sequentially add the coffee, vanilla extract and vegetable oil and whisk until combined. Alternately add the flour mixture and milk in to batches respectively and beat in medium-low speed until the batter is smooth without lumps, approx. 1 minute. |
| 5. | Add 1/3 of the meringue to the egg yolk batter and mix with a rubber spatula. Then pour the egg yolk batter into the Meringue. Gently fold the mixture in a down-cross-up-and-over motion until the meringue and egg yolk batter are combined. Do not over-mix. Pour the cake batter into the baking pan and smooth the surface with a pastry cutter. Knock the pan on the counter several times to get rid of the air bubbles. |
| 6. | Place the pan on the middle rack of the oven and bake for about 20 minutes, or until a toothpick comes out clean after you inserted it into the center of the cake. |
| 7. | Remove the pan from the oven. Carefully flip the cake onto another piece of parchment paper. Gently peel the parchment paper away from the cake. Score three lines (2cm apart) along the edge of one short side. Do not cut all the way through. Spread the whipped cream all over the surface of the cake, leave 1" gap at the end. |
| 8. | Roll the cake from the narrow side closed to your body over the filling to the other end. Wrapped the roll with a piece of food plastic wrap and store in the fridge for at least 2 hours before serving. |
