Mochi are sticky glutinous rice balls that are either coated in mixture of sugar, nuts and corn flour, or stuffed with fillings such as red bean paste, ice cream or custard. Making mochi is a fun weekend activity to share with the kids, as you can mould and stuff the rice balls with your favourite paste, before indulging in this bouncy, chewy snack. This time though, you don't have to eat it the traditional way-stuff it into a delicious crisp chewy cookie for extra indulgent fun too. If youre out of corn starch, simply replace it with twice the amount of tapioca starch or flour.
