Line a cake pan with aluminum foil, and cut a piece of parchment paper to fit the bottom of the pan. Dust with strong flour.
Heat and stir milk, honey and vegetable oil until the honey melts, but don't boil.
Separate the eggs. Beat the egg whites with half of the sugar, until peaks form. If you add the sugar in three batches and beat the egg whites over a bowl of hot water, it will turn into a stiff meringue. Make sure the eggs don't get too hot!
Add the other half of the sugar to the egg yolks and beat well until the mixture becomes light-colored.
Add the milk mixture from Step 2 to the egg yolk mixture, and blend well. Then add the flour, and mix well with a whisk.
Using a whisk, add a dollop of meringue from Step 3 to the batter made in Step 5, and mix in, scraping from the bottom of the bowl. Repeat twice.
Fold in the remaining meringue with a rubber spatula in 2-3 batches, scooping it up from the bottom of the bowl. Mix until the white of the meringue is blended in.
Pour the batter into the cake pan. Gently drop the pan onto the countertop from 10cm, to remove air bubbles. Bake in an oven preheated to 350F/180C for 10 minutes, lower the temperature to 285F/140C and bake for 50 minutes, or until a skewer inserted in the cake comes out clean.
Take it out of the pan and let cool with the foil on. When it's cool, remove the foil, invert the cake, and wrap in plastic wrap for about half a day, so it sets and becomes moist.
This is a piece I cut in half, without the edges.
Story Behind this Recipe
I used user "Bekuchin"'s recipe and changed the order to make it easier for me to make, because the first time I made it I found it hard to mix the flour into the egg yolks... It's made almost the same way as chiffon cake.
If the bowl is not completely clean and dry when you make the meringue, the egg whites will not form stiff peaks. Be sure to wash and dry the bowl before use. When I put the egg whites over hot water, I use the "keep warm" setting on my induction stovetop. Three minutes at this setting is just right. Then, I take the bowl off the hot water, and beat the egg whites.
