This is so far the most challenging bake that I've done apart from the Macarons ~! Especially for the husband's birthday... took 3 days to complete the whole bake since I'll be at work most of the time ...
I used an 8 inch pan to bake the bottom layer of the cake and a 6 inch cake ring to shape it.
Mango Puree
8 medium size mangoes / 1 litre bottle from Phoon Huat
For using fresh mango puree:
Remove skin and cut out the pit. Cut mango flesh into pieces. With a small food proccesor, puree mango until smooth. Set aside. (Leave it in the freezer if you are doing this few days ahead)
Mango Jelly
200ml mango puree
3 sheets (6 grams) gelatin (I used Gelatin leaf from Phoon Huat)
To make mango jelly:
- Soften the gelatin in a bowl of cold water.
- Warm mango puree in small saucepan. The puree should be warm and not boiling. Remove from heat.
- Squeeze the excess water from the gelatin. Stir it into the warm mango puree. Pour mixture into holes of mini muffin tin (use a mould/bowl smaller abt 3-4 inches)
- Freeze mango jelly until completely frozen. To unmold, dip bottom of mould/bowl tin in a tray of hot water for 5 secs. Flip mould/bowl upside down on a baking paper and give a gentle shake to get the mango jelly out. Return the unmolded mango jelly rounds back into the freezer immediately until ready to assemble.
Sugar Syrup
150ml water
100 grams caster sugar
2 tablespoons of orange liqueur (cointreau) - got a small bottle from Phoon Huat
To make sugar syrup:
Combine water and sugar in saucepan, stir, over medium heat until sugar dissolves. Allow to boil for 5 seconds. Cool completely before adding orange liqueur.
Sponge
90 grams egg whites
80 grams caster sugar
80 grams egg yolks
40 grams cake flour
20 grams corn flour
35 grams unsalted butter, melted
To make sponge:
- Preheat the oven to 200C (or 180C fan-forced). Line 30x20cm cake pan ( I used a brownie tin) with baking paper.
- Whisk egg white until foamy. Add one quarter of the sugar and whisk for a while. Then add remaining sugar and beat until stiff peaks form and egg whites are glossy. Add egg yolks and whisk until combine.
- Combine and sift both flours. Gently fold flours into the batter with a spatula until combine. Fold in melted butter until combine.
- Pour batter into the prepared pan, spread evenly, and bake for 15 minutes or until when a toothpick is inserted in the center comes out clean.
- When sponge is done and cooled, peel away (by gently rubbing) or slice the layer of brown skin on the top.
Mango Bavarian Cream
3 sheets (6 grams) gelatin leaf
2 egg yolks
50 grams caster sugar
125ml mango puree, room temperature
200ml whipping cream
To make mango bavarian cream:
- Soften the gelatin in a bowl of cold water.
- Whisk egg yolks and sugar in a heatproof bowl until pale and creamy. Add mango puree, and whisk to incorporate. Place bowl over a saucepan of gently simmering water, whisk constantly, until the mixture reaches 85C. Remove from heat.
- Squeeze the excess water from the gelatin. Stir gelatin into the mango mixture until gelatin completely dissolves. Strain the mixture through a sieve into a bowl. Place the mixture over a bowl of water with ice. Stir mixture until it cools to room temperature. (Alternatively, place cling wrap over surface of mixture, and place in freezer for about 5-10 minutes until it cools.)
- Meanwhile, use a frozen stainless steel bowl and whisk cream to firm peaks (be careful not to overwhip). When the mango mixture cools completely, carefully fold whipped cream into the mango mixture with a spatula until combine.
- At this stage, start assembling the entremet. The bavarian cream needs to be use immediately before the gelatin start to take effect.
To assemble (1):
- Line a cookie tray (or any rectangular baking tray) with baking paper. Place 7.5cm diameter X 4.5cm height cake rings/ 6-inch cake ring on top. You will need 6 cake rings (only 1 if you are using 6 inch).
- Cut out sponge cake using the cake ring. Brush sponge generously with sugar syrup. Place sponge in the cake ring.
- Place the frozen mango jelly on top of the sponge. Pour mango bavarian cream over, and level with a spatula. Place in freezer until completely frozen.
Mango Glaze
100 grams white chocolate, finely chopped
4 sheets (9 grams) gelatin leaf
100ml mango puree (after strain through a sieve)
50 grams caster sugar
100 grams liquid glucose
70ml whipping cream
Optional: 1 or 2 drops of yellow food colouring
To make mango glaze:
- Melt the chocolate in a bowl over, not touching, simmering water. Stir occasionally to assist the melting. When the chocolate has melted, remove from the heat and set aside to cool.
- Soften the gelatin in a bowl of cold water.
- Combine mango puree, sugar and glucose in a saucepan over medium heat, stir until sugar and glucose disolves, and mixture starts to boil. Remove from heat.
- Stir cream into the syrup mixture. Squeeze the excess water from the gelatin, and stir gelatin into the syrup mixture. Pour over the melted chocolate, then stir gently to combine. Add yellow food colouring if required.
- Allow glaze to cool to room temperature. The glaze will thicken as it cools to the right temperature. To check if the glaze is ready to use, dip spoon into the glaze. The glaze should coat the back of the spoon. Use glaze immediately.
To assemble (2):
- Unmould entremets from cake rings. (Tip: To unmould, I place the entremet, still in the cake ring, in a ziplock bag. Slowly lower the ziplock bag into a bowl of hot water, careful not to get water in the bag. Leave ziplock bag in the hot water for 5 secs, then quickly lift the bag out of the water, take the entremet out, and gently push the entremet out of the cake ring.)
- Place entremets on a cooling rack set on a baking tray line with baking paper. Working very quickly, and in a confident and smooth motion, pour glaze over frozen entremet. Do not meddle with the glaze as it sets very quickly.
- Allow entremets to thaw in fridge for 4-6 hours before serving.
- 230 g white chocolate, coarsely chopped ( I used cadbury )
- ¾ cup heavy whipping cream ( I used thickened cream from NTUC)
- 2 tbsp unsalted butter
- ¼ cup mango puree
- For the mango white chocolate ganache, place the chocolate in a heat-resistant bowl. Bring the heavy cream to a to a simmer in a heavy-bottomed pot over medium heat. When bubbles start to form along the sides, remove from the heat and pour over the white chocolate. Allow to sit for a minute before stirring to combine. Whisk in the butter until completely melted. Stir in the mango puree until well combined. Refrigerate overnight, or until set.
- Remove from the fridge and whip until slightly thickened, about 3-4 minutes. Pipe onto half of the macaron shells and then sandwich with a second shell. Allow to chill for a few hours to set before serving.
