Tôm rim (caramelised prawns)
Tôm rim is a homely dish cooked in kitchens from Hanoi to the Mekong Delta and eaten at the family rice tray with boiled greens and a clear soup: prawns simmered down in fish sauce, sugar and shallot until the liquid turns to a sticky, salty-sweet glaze. The mistake is walking away in the last few minutes, when the sauce goes from glaze to burnt very quickly. Chef's tip: leave the shells on if your prawns are small, as many Vietnamese cooks do; they turn crisp and caramelised and add flavour.
