Jerusalem artichokes are easy to grow, they’re part of the sunflower family and are very undemanding on the gardening front. Pop the tubers into the ground and after that they pretty much look after themselves.
We grew Jerusalem artichokes last year and then forgot about them until last week when I went on an exploratory dig and discovered lots of knobbly roundish roots. They were in great condition and there are plenty of them. It’s presented the dilemma of what two do with them. Luckily they don’t all need to be eaten at once , they look quite comfortable in the bucket, muddy but dry, and will hopefully sit for a while whist we eat them up.
First up I made a gratin. I mixed some with potatoes, spinach, leeks and Tallegio cheese. This was adelightful combo, creamy, cheesy and very tasty with the sautéed leeks and spinach layered through and perfect eating for this weeks wet and wild weather. We ate the gratin after a beetroot and blood orange salad which is why the plate is pink.
One of the properties of Jerusalem artichokes is that they have a high content of inulin. Inulin has lots of dietary bonuses; plenty of fibre which in turn is helpful in managing diabetes, constipation and general gut health but they really should come with a warning. These powerful vegetables have great flavour but are also very windy. All that fibre causes mighty flatulence. Our duvet almost hit the ceiling when we went to bed. I guess it’s the type of vegetable to be only eaten with close family or friends – they aren’t known as fartichokes for nothing. Apparently if you eat them little and often you can override this side affect so I guess we need to proceed through the stash and see what happens.
The gratin was delicious!
600g jerusalem artichokes
1tbs olive oil
250g fresh spinach
a small bunch of thyme
250g Tallegio cheese
salt and pepper
Peel the potatoes and artichokes then slice very thinly. Put them into a big bowl. Drizzle over little olive oil, season with salt and pepper and add the thyme. Toss well .
Clean the leeks then slice small. Wash the spinach and trim any big stalks. Put a saucepan with little butter on the heat, add the leeks and when it begins to sizzle turn the heat low and cover with a lid. Shake very couple of minutes until the leeks soften then stir in the spinach. Cover again with the lid and cook for 2-3 minutes until the spinach has wilted down. Season with salt and pepper.
Pre heat the oven 190c
Rub a little butter or olive oil around a gratin dish put in a layer of half the potatoes and artichokes then add the spinach and leeks. Break the tallgio into small pieces and distribute over the top then layer up the remaining potatoes and artichokes.
Put the cream into a small saucepan and bring too the boil. Pour the cream over the vegetables. Cover the gratin dish with a piece off aluminium foil then bake for 50 minutes. Remove the foil and bake for another 15-20 minutes or until the top of the gratin is golden.
Allow to sit for 10 minutes before eating. The ideal amount of time to consume a salad.
