apart from matcha, goma black sesame would perhaps be my 2nd most favorite japanese-inspired flavor. having made a few chiffon cakes now (rose, pistachio raspberry, matcha, purple sweet potato), i can't believe i waited so long to make a black sesame one coz this is by far, in my opinion, the best chiffon cake i've made.
i wouldn't actually hv thought of making my own vanilla sugar since i feel that using new pods for this is just too extravagant. old ones hv all gone into my homemade vanilla extract so there wasn't any opportunity to make this until i found some unused ones in my fridge. due to my carelessness i had forgotten to wrap them tightly so they had dried out, which is just perfect for the task if you ask me!
