I saw this on Masterchef Australia this week and just had to try it. It was £7 on Amazon(!), but hey, I love trying new foods.
I knew from the show it is Japanese, so I got out my Japanese book Everyday Harumi which I'd only cooked two dishes from.
I chose the chicken karaage, crab fried rice and sesame green beans.
The rice was way too stodgy when cooked, and I knew it wouldn't fry well at all, so I imrovised and made it into a cogee, using mirin, dashi wasabi and topping with sliced spring onions.
It was delicious, but then we love congee.
The karaage was great-fried chicken always is, and the beans added a great freshness and crunch.
The kewpie is much tastier and tangier than normal mayo we thought, I have another recipe using it lined up for later this week.
