I made this cake for my Aunt for her birthday. My cousin who came from Hong Kong loves chocolate.so I used chocolate as the main ingredient and paired it up with a layer of strawberry yogurt cheesecake .
這是EC做給姑媽的生日蛋糕，愛吃朱古力的表妹從香港回來探望家人，因此EC選了朱古力作主材料，再以一層士多啤梨乳酪芝士蛋糕作配搭。
Do use high quality chocolate (such as couverture chocolate) if you can afford it. My chocolate mousse mainly consists of chocolate and whipping cream, together with a hint of salt, vanilla bean paste and cocoa powder to boost up the flavor. There is so much chocolate that no gelatin is required to set the mousse. If superior chocolate is used, I’m sure your guests will rave about your cake.
可以的話，EC建議使用能力以內負擔得起的優質朱古力(EC使用調溫朱古力)。朱古力慕絲材料就只有朱古力和淡忌廉，另添少量鹽、雲尼拿醬與可可粉提升味道。朱古力的用量經己足夠令慕絲凝固，因此食譜不需使用魚膠粉，朱古力品質越高，味道自然越好。
For the almond sponge cake I switched from melted butter to grapeseed oil. From my previous experience (read about my posts, Chocolate Delight and Coconut Yam and Mango Mousse Entermet), I found that butter made the cake dry and extra syrup had to be brushed on in order to maintain moisture. This time my sponge cake strips were all moist and soft and I will continue to use oil in the future.
杏仁海綿蛋糕方面，EC以葡萄籽油取代牛油，過去的經驗告訴EC牛油做的圍邊較乾，需要掃上糖水保濕(詳情可參考朱古力五重奏或椰香紫薯配芒果慕絲蛋糕)，但今次改用液體油後蛋糕一點兒也不乾，所以EC會繼續使用液體油。

Directions 做法
For the Chocolate Decor Paste 朱古力糊
In a small bowl, beat egg white and icing sugar with a whisk until smooth. Whisk in melted butter. Combine and sift flour and cocoa powder in another bowl. Add to first mixture in two batches and fold to combine. Do not overmix. Refrigerate for 10 mins if the paste appears to be too thin.
小碗中放蛋白和糖粉用蛋拂拌勻，加牛油溶液拌勻，麵粉和可可粉混合過篩放在另一碗中，分兩次加進蛋白楜中輕輊拌勻，切勿過度攪拌，若麵糊過稀可冷藏十分鐘才使用。
With an offset spatula, spread paste evenly on a silicon baking mat that is the same size as the baking pan. Create designs with fingers or a pastry comb (I dragged my Ateco pastry comb through the paste to make stripes). Transfer mat onto a baking sheet then freeze for 15 minutes or until the paste is firm.
用曲柄抹刀將朱古力糊平均地塗滿矽膠墊(需與方形焗盆相同大小)，在表面用手指或刮板畫上花紋(EC用Ateco刮板拉出條紋)，將矽膠墊放在烤盆上，放入冰箱十五分鐘或至硬。
For the Joconde Sponge 杏仁海綿蛋糕
In a mixing bowl, beat almond flour, icing sugar, whole egg and egg yolks with a hand mixer until pale and thickened. Fold in sifted flour followed by the oil. In another clean bowl, whip egg whites with a hand mixer until soft peaks. Add sugar and beat until firm (but not stiff) peaks form. Fold into the egg mixture gently.
杏仁粉及糖粉混合過篩放在鋼盆中，加入全蛋及蛋黃用電動打蛋器打發至淺黃色及稠身，先後加入過篩麵粉及油以切拌方法混合，蛋白放在另一清潔的鋼盆中，用電動打蛋器打至軟勾狀，加入糖繼續打至企身，加進蛋糊中輕手以切拌手法混合。
For the Joconde Imprime 杏仁蛋糕裝飾圍邊
When the chocolate paste is firm, remove baking sheet from freezer and transfer mat into the square baking pan. Pour the joconde batter over the frozen paste. Spread evenly with an offset spatula or bench scraper to cover the entire design.
從冰箱取出已雪硬的朱古力糊，把矽膠墊放進方形烤盆內，將海綿蛋糕麵糊倒在花紋上，用曲柄抹刀或刮板抹平，花紋必需完全被掩蓋。
Bake in a 325°F/160°C preheated oven for 15 minutes or until the cake springs back to the touch. Remove from oven. Immediately loosen the sides and flip cake out of pan onto a piece of parchment paper. Lift up silicon mat carefully and transfer cake to a wire rack to cool completely. With a ruler and a sharp knife, trim cake into 1.75” wide strips. Keep cake strips covered until ready to use.
放入325°F/160°C預熱焗爐十五分鐘或至用手按蛋糕表面會回彈後取出，立即脫模反轉放在牛油紙上，小心撕去矽膠墊後轉移到鋼架放涼，用間尺及小刀將蛋糕切成1.75寸寬長條，用保鮮紙蓋好備用。
For the Chocolate Chiffon Cake 朱古力戚風蛋糕
Sift together the flour and cocoa powder into a mixing bowl. Mix well and make a well in the center. Add oil, milk, egg yolks, and vanilla bean paste to the well and whisk gently until combined.
低筋麵粉及可可粉混合過篩放入鋼盆中，將粉往周圍撥成粉牆狀，將油、牛奶、蛋黃及雲尼拿醬倒進粉牆中央，輕手用蛋拂攪拌成蛋黃糊備用。
In a clean, separate mixing bowl, whip egg whites with a hand mixer until foamy. Add cream of tartar (to stabilize the meringue) and continue beating until soft peaks form. Then slowly add sugar in batches and continue beating until glossy and firm peaks form. Scoop about one third of the meringue to the yolk mixture and mix well to lighten. Then pour this back to the remaining meringue. Fold gently and thoroughly until you see no streaks of white.
取另一清潔的鋼盆放入蛋白，用電動打蛋器將蛋白打至起泡後加入他他粉繼續打至泡泡變細密，分次加糖打至企身接近乾性發泡，將三分一蛋白霜混入蛋黃糊中充份拌勻，再將麵糊倒入餘下的蛋白霜中用膠刮輕手以切拌方法混合至麵糊成均一的顔色。
Pour batter into pan and smooth top with a spatula. Tap cake pan against the kitchen counter several times to get rid of any large air bubbles. Bake in a 325°F/160°C preheated oven until a wooden skewer inserted into the center of cake comes out clean, about 20 to 25 minutes for my oven. Invert the cake pan and cool completely on a cooling rack before unmolding. Slice cake to about 1/2 inch thick. Keep covered with plastic wrap until ready to use.
將麵糊倒入模中，用刮刀抹平麵糊表面，將烤模往枱上輕敲幾下敲出較大的氣泡，放入325°F/160°C預熱焗爐焗至竹籤插入蛋糕中央取出不沾麵糊, EC家中焗爐約需20-25分鐘，取出十分鐘後可脫模及轉移到鋼架放涼，用刀切成半吋厚蛋糕片，以保鮮紙蓋好備用。
For the Dark Chocolate Mousse 黑朱古力慕絲
Chill a mixing bowl and the whisk attachment in the freezer for 5 to 10 minutes before you start. Mix cocoa powder, salt and hot water in a small bowl until thoroughly combined.

鋼盆及打蛋器配件預先放冰箱五至十分鐘雪凍，小碗內放可可粉、鹽和熱水開勻，拌入雲尼拿醬，黑朱古力隔熱水坐溶或放微波爐用中火叮溶，加入可可粉溶液拌勻放涼。
With a hand mixer, whisk whipping cream in the chilled mixing bowl until soft peaks. Fold whipped cream into chocolate-cocoa powder mixture in two batches until no white streaks remain.

放至微暖(122至140ºF/50至60ºC)後拌入魚膠溶液，過篩去除顆粒備用。
To Assemble 組合
Wrap the bottom of the cake ring with plastic wrap. Line the inside with acetate or parchment paper strips for easy unmolding. Wrap the inside of the mold with joconde imprime cake strips, decorative side facing out, with the ends slightly overlapping each other. Press ends firmly together to seal the seams. Trim the chocolate chiffon cake slightly so it fits into the ring. Place cake layer inside the ring. Spread dark chocolate mousse over until about 2/3 full. Tap ring against the kitchen counter to get rid of air bubbles and smooth top. Refrigerate until mousse has set.
慕絲圈底部包上保鮮紙，內側圍上透明圍邊膠條或牛油紙條方便脱模，把杏仁蛋糕圍邊圍在慕絲圈內(圖案要向外)，壓實重疊的邊緣，朱古力蛋糕片剪裁至適當大小後放在慕絲圈底部，倒入朱古力慕絲至2/3滿，將圈往枱上拍幾下震掉大氣泡後抹平表面，放入雪櫃冷藏至慕絲凝固。
Remove the chilled cake layer from the fridge. Arrange strawberry slices over the chocolate mousse. Pour strawberry yogurt cheesecake over. Tap ring against the kitchen counter to get rid of air bubbles and smooth top. Refrigerate until set.
從雪櫃取出蛋糕，把士多啤梨片排放在慕絲表面，倒入士多啤梨乳酪芝士糊至九分滿，將圈往枱上拍幾下震掉大氣泡後抹平表面，放入雪櫃冷藏至凝固。
Remove chilled cake from the fridge and pour the chocolate glaze over. Return to the refrigerator and chill until glaze has set. Unmold and decorate with fresh fruits. Cut into slices and serve.
