To make a pulp mix strawberries, sugar, salt and bring to boil. Take off from fire and chill. Set jelly as per instructions on the packet. Just before serving - in a blender add pulp (made as above), jelly chunks, colour, essence and water. Blend very lightly. Pour into glasses and mix in finely crushed ice. Use wide straw for serving. For variations use different fruits with matching jellies, colours and essences. Eg. pineapple, orange, grape, etc.
