This little savoury sounds rather odd when scanning the ingredients,
but it's really very tasty. If nothing else it will give you the
opportunity to sample an interesting and delicious fish paste, quite
unlike the commercial varieties.
Make sure oatcakes are hot.
Melt butter in a pan, add egg yolks, egg white, fish paste, pepper.
Stir until thick. Pile mixture on top of oatcakes.
Sprinkle with browned breadcrumbs; serve immediately.
