These are black tiger prawns from south east Asia. They're 10 to 12 times the size of cold water prawns (such as our Best North Atlantic prawns) and they have an excellent firm texture verging on crunchy. Add a little mayo or something fancier, and you have an A-grade eating experience. About 20 prawns per pack, or 75 in the saver pack.
You will find similar looking but less expensive prawns on other sites, but when comparing prices consider the SIZE of the prawns and the GLAZE (that's the water "overcoat" added to each prawn). Our weights exclude the glaze and we always offer the largest available size.
