I recently used dried shrimps in a recipe but they were hard, like stones, and I wondered what was the point of including them?
There are two ways of dealing with dried shrimps. Either soak them in hot water for 15 minutes, or soak them in cold water for about two hours. When we tested the recipes, we found no difference with the finished shrimps and they were certainly never like 'stones'. I wonder which variety you used – we used Lucky Brand. Dried shrimps are often included in recipes because they have a lot of concentrated flavours, unlike the frozen varieties of prawns.
