Honey & mustard is good too
Caramelised onion
Apple is a favourite in this house - just add freshly grated apple that's had a squeeze of lemon juice on it.
Pork & stilton
(wrap the sausagemeat around a thin slice, so you get a melting middle
)
Spicy cajun (just using a pre-made seasoning)
Sweet Chilli
(Use a pre-made sweet chilli sauce and put in some blanced thinly sliced spring onions)
The possibilities are endless
I make mine with the same base as sausages - 70% pork, 20% fat, 10% rusk/breadrumbs and an egg to bind it together (or 2, if it's a big batch)
HTH & good luck
