Coffee Chiffon Cake

I have 2 books on chiffon cake but at times I find their variation kinda strange like Filament Stick (which is the white fish crabstick), Popcorn Chiffon, XO Sauce Chiffon?! I was running out of ideas on the chiffon variation and remember I had a pack of Mocca Instant Coffee around and went ahead to prepare all the ingredients to realise it has expired! I substituted instant coffee powder as what the recipe ask for. And I broke 2 eggs in the midst of it … maybe not a day to bake? With half of the ingredients weigh and prepare, I went ahead.

The original recipe call for 2 eggs but I added another 1 more egg white for the volume. The texture is really soft, fluffy and cottony. A pity that the coffee scent is not strong, I will try to get some good coffee and try again.
