* If you put in a piece of salmon it will add great flavour!
NOTES : The paste below is not a Scottish dish; it's Chinese. It's included because Scotch Toast calls for it and most of the commercial fish or 'bloater' pastes available are mediocre. Scottish cooking has a long tradition of borrowing from other cultures and this recipe is being borrowed from China because it's easily made, versatile, has no fishy flavour and most importantly, is delicious!
