Uni Omochi

I couldn’t walk by this.  Omochi (cake made out of pounded rice) flavoured with Uni (sea urchin roe).  It has the colour and flavour of uni but the texture of soft chewy omochi.  Sort of a departure from sweet versions and still very delicious.  I am guessing that the options for flavouring omochi are endless.  Sweet, savoury salty or spicy all work well with it.  Is there anything you can’t do with omochi?
