For us, living in Kajang for many years, Semenyih has been synonymous with Cucur Udang (fried prawn patties) since the time we were in school. Considering that we left school some 25 years ago, that's a pretty long time. And the place that put Semenyih on the food map is an un-named stall located near the Semenyih field (beside the Sekolah Kebangsaan China Semenyih) which is referred to by locals as "Malek Tauhu". We just call it the 'Semenyih cucur udang' place.
I love the chili sauce so much that I save any balance in a bottle in my fridge ! Give it a try if you're in Semenyih. The stall is now run by Malek's daughter who handles the cutting and sales of the taufoo and cucur udang. The speed that she can cut these is quite amazing - something perfected over many years of practise (and clearing long queues no doubt).
Location : Stall beside the Semenyih field (near SK (C) Semenyih. Open from about 11.00 a.m. until about 4.00 p.m. Very crowded at lunch time.
