Pork is a very flexible meat and can take on flavours of all kinds to great effect...
Apples and Pears - the sharp sweetness of apples can really cut through the fattier flavours of the pork.
Thyme and Parsley - both classic flavours that just work incredible well.
Lentils - The dense grainy texture of the lentils just goes well, especially with pork belly.
Sage - another simple sophisticated classic.
Garlic - similar to the sharp sweetness of apples it cuts through and draws out the flavour.
