All you need

I use this Bosch 8 series oven. Preheat to 180℃. 

KitchenAid Mixer 5Q

Speed 4, all the way for making meringue.
Once you start beating the egg white, start the timer.
Trehalose has less sweet flavor. Added 1/3 of trehalose into egg white
around every 1 min. Stiff meringue will make the batter hard to mix,
and the cake may become drier. I'd like to beat the meringue for about
70~80% stiff. This will take total of 7~8 mins. 

Beat the egg yolk.

Add sugar and mix till dissolved.

Add water and mix for a couple of seconds.

Add oil and mix well.

Sifted flour.

Add all the sifted flour and mix well till smooth.

After 7:30 mins of mixing, the meringue looks like this.
This is a little too stiff for me.

The egg yolk batter.

Add some (1/3) meringue into egg yolk batter and mix well.

Pour (the egg yolk batter+1/3 meringue mix) into the remaining meringue
and gently mix well.

Pour earl grey paste into a bowl.

Add some cake batter into the paste.

And mix well.

Pour the mix into cake batter and mix well again.

Pour cake batter into the mold.
This chiffon cake mold is 17 cm round. It is a higher mold usually needs 4 eggs.

After 10 mis of baking, you can take the cake out and draw lines.
Or you can skip this step and let the cake crack some lines by itself.

After done baking, take the cake out,  put it upside down and let it cool down.
I will cover it with plastic wrap and put it in refrigerator for 20 mins
before unmold the cake.
