In a bowl flake the snoek and remove all bones. Add the corn, cheese, chili and coriander and mix. Add the mayonnaise, taste and adjust seasoning.
Use only one of the rolls from the packet. (Phyllo normally comes on two separate rolls in a box.)
Remove the phyllo from the plastic and lay all layers flat on a work surface.
Cut down the middle of all the layers.
Now start brushing the top layer with butter.
Turn the top layer over, so that you now have two layers “glued” together with the butter.
Use a spoon and put the filling in a thin line on the long end of the pastry.
Roll up and then roll into a spiral. Secure with a kebab stick and place on a baking sheet, lined with baking paper.
