Goes very well with any form of eggs, not just soft-boiled ones: especialy if you spread it on toast underneath scrambled or poached eggs.
My husband still eats it with strawberry jam, and will insist on putting it in the gravy which makes it far too salty ( the source/sauce of many family arguments!).
You can make it into a hot drink also as it dissolves well in boiling water: and you can now get it in cubes.
A friend who has coeliac disease tells me that either Bovril or Marmite is OK for coeliacs, but the other isn't: can't remember which is the offender, however!
