Watermelon ice cream cake recipe 爽 すいかアイスケーキ

We set out to make a chilled desert that looked like a watermelon, using watermelon flavored ice cream. Our yearly watermelon dessert. This is Mosogourmet’s 2015 version. The watermelon filling tastes good frozen, but can also be eaten as-is, or be re-cooled in the refrigerator to enjoy later. It’s delicious out of the freezer and just beginning to melt, too. There were a series of mishaps, like the consistency not coming out right and requiring a do-over with more gelatin, and the sponge floating on the filling, but we ended up with a fun dessert!
スイカ味のアイスクリームを使って作る、見た目がスイカみたいな冷たいデザートを作ってみました。毎年、恒例のスイカデザート。コレが妄想グルメ、2015年バージョンになります。スイカ味のフィリングは冷凍してもよいのですが、そのまま食べたり、冷蔵庫でさらに冷やしても楽しめます。冷凍庫から出して、溶けかけをいただくのもオイシイですよ。濃度がつかなくてゼラチンを増やして やり直したり、スポンジがフィリングに浮いてしまったりとハプニング続きでしたが、楽しいスイカデザート できました!レシピは長かったのでアメブロで http://amba.to/1VMrNRj

*Recipe*
Bake sponge cake
1. Line a 27 cm square baking pan with parchment paper, and coat with a thin layer of oil.

First, bake the green sponge cake
2. Divide the white and yolk of 1 egg.
3. Beat the egg white briefly with a mixer until it has turned entirely white. (Hand mixer on high speed.)
4. Add in 25 g of granulated sugar and beat thoroughly until peaks form.
5. Add in the egg yolk and mix again.
6. Dissolve 3g (1 1/2 tsp) of matcha in a small amount of hot water. Mix into egg mixture.
7. Sift in 13 g (1 2/3 tbsp) of cake flour, combine briefly at a low speed, then switch to a rubber spatula, and mix thoroughly until the flour is fully incorporated.
8. Pour your mixture into the pan from Step 1, and level it off.
9. Tap the pan on the counter to remove any large air bubbles, then bake for 4 1/2 minutes in a 200° preheated oven.
10. When it has finished baking, cover it with parchment paper or something to keep it from drying out.

Next, bake the white sponge cake
11. Divide the whites and yolks of 3 eggs.
12. Mix the same way as you did in Steps 3–5.(Granulated sugar 75g)
13. Sift in 37 g (4 1/2 tbsp) of cake flour, combine briefly on low speed, switch to a rubber spatula, and mix thoroughly until the flour is fully incorporated.
14. Pour this mixture into the pan from Step 10, and level it off.
15. Tap the pan on the counter to remove the large air bubbles, then bake for 6 minutes in a 200° preheated oven.
16. When it has finished baking, cover it with parchment paper or something to keep it from drying out.

Use watermelon ice cream to make the filling.
17. Once your sponge cake has cooled from Step 16, cut it into 2.5 cm wide slices, and cut the slices off diagonally at each end. (You will use two slices, plus about 7 cm.)
18. Line the circumference of the mold with parchment paper.
19. Place the pieces from Step 17 into the mold, as if trying to stick them to the paper, leaving no gaps.

20. Sprinkle 13 g of gelatin into 50 ml of water, and allow it to soak.
21. Heat the mixture in the microwave for about 30 seconds to dissolve the gelatin. (Do not let it come to a boil.)
22. Warm 140 ml of milk without letting it boil.
23. Mix the gelatin mixture into the milk.
24. Mix in 35 ml of watermelon syrup.
25. When that has cooled, add two packages of watermelon ice cream (380 ml / 310 g) and use mixer to blend.
26. Pour the mixture into your mold from Step 19, and allow it to cool and harden in the freezer for about 8 hours.
27. Draw on the black watermelon rind stripes with black cocoa powder melted into a small amount of water.
28. Slice and enjoy.
