In my eyes, mentaiko is matchless. It goes well with almost everything, ice cream included. This limited edition mentaiko soft serve ($6.90) isn't as absurd (or fishy) as it sounds!
First few adjectives that immediately came to mind: umami, sweet, buttery. At times, it tasted as though I was merely eating vanilla ice cream, but in those unassuming moments, spice would creep in, tickling the back of my throat. The addition of furikake sprinkles took the 'savoury' aspect up a notch, helping to tone down the initial surge of sweetness. Yes, I downed the entire cup in a matter of minutes.
If you aim to become an adventurous eater one day and need a place to start, this is it. Baby steps, baby steps.
