Singapore Prawns with Bugis Street Sauce

I haven’t been back to Singapore since 1948 but I always remember those marvellous prawn dishes I had in Bugis Street. This recipe is the nearest I can get to one of the sauces. There was always a side dish of small red chillies and one of our friends would chew these as if he was eating peanuts. The more reserved of us would take one or two.
