When people in NZ say "sweet as" I like to say something sweet.
Sweet as...

12 days into a no sugar only dairy and carb diet you sneak to the fridge in the middle of the night and there's a bag of grapes that you accidentally bought because you forgot that fruit has sugar. And you didn't want to throw them away fresh so you just leave them in the fridge until they go bad. And you feel through the bag and most of them are soft but then you find one that's perfectly firm. And you feel it like you're feeling a baby.
I like making people tase things by using words. Good food is probably better than bad.
