Yea, bukan semua udang perlu sembunyi di sebalik batu (not all prawns need to hide behind a rock). In this case, they were nicely stuck to the top of the yummy old-time delicacy known as Cucur Badak.
Half a century back, while I was in primary school, I ate a piece of this nearly everyday at the school tuckshop, where the ‘kak-and-makcik’ team sold a variety of traditional Malay kuih. Adoih, Sedapnya !
These days, rather few people in Singapore have heard of this stuff, fewer still have eaten one. Even on rare occasions where these are encountered, cost-cutting has taken a toll : one can toss the round things around, look di hadapan, di sebalik, tapi cannot find any Udang.
