Jerusalem artichoke is a quirky little vegetable.
A quirky little vegetable, these knobbly tubers have a unique taste that can probably best be described as a combination of potatoes and globe artichokes. Treat them as a stand-in for spuds and you can’t go wrong.
Jerusalem-artichoke and black-garlic mash with cod, kale, Parma ham and kale-pesto mayonnaise (serves 4)
600g Jerusalem artichokes
3 cloves black garlic (normal will do, but reduce to 1 clove as black is mellower)
4 cod fillets (about 120g each)
4 slices Parma ham
4 handfuls kale
3 handfuls kale, stem removed
150g Parmesan, grated
Juice and zest of 1 lemon
75g pine nuts
2 cloves garlic
100ml olive oil or more if needed
Preheat your oven to 180°C/350ºF/gas mark 4. Peel the Jerusalem artichokes and cut into even-sized pieces, then simmer in salted water until tender. Drain well. Add the black garlic and a good splash of olive oil, then use a stick blender to make a purée. Keep warm until ready to serve.
To make the pesto, add the kale, Parmesan, lemon, pine nuts, garlic and olive oil to a processor and blitz into a coarse paste. Taste, add seasoning and set aside.
Next, place the cod fillets on a baking tray, season and smear with pesto. Crumple a slice of Parma ham onto each fillet and bake for 20 minutes.
While the fish is in the oven, boil your kale in salted water for a few minutes. Drain well and toss with a spoonful of pesto.
Serve the cod with the Jerusalem-artichoke mash and kale. Add mayonnaise to the remaining pesto, mix well and serve on the side.

A side of Jerusalem artichokes
Arrange 500g of peeled and roughly chopped Jerusalem artichokes in a baking dish.
