This extraordinary vegetable, with its polished purple exterior, begs to be cooked and, at the moment, British aubergines are seasonal and delicious. Now they are accepted as succulent, filling vegetables but there were times when aubergines were regarded with suspicion.

For centuries, aubergines - like potatoes, tomatoes and peppers, a member of the nightshade family -were eaten in India and other Asian countries. Europeans remained sceptical - maybe because of the deadly nightshade connection.

While Italian Jews ate aubergines, others feared if they followed their example, they would go mad. Hence the Italian name melanzana, meaning "mad apple". And even though the Jews were expelled from southern Italy in the 1500s and escaped to the north, gradually, Italians up and down the peninsular - probably tempted by the looks and fragrance of their dishes and the ease with which this prolific vegetable could be grown - learnt their recipes and cultivation techniques, and were finally converted.

It used to be said that it was necessary to cut the aubergine and salt it to remove the bitter juices. But modern horticulture has produced wonderful varieties that do not need that process. However if the aubergine is not treated before frying, it will absorb oil like a sponge and can be indigestible.

But there is a way around this dilemma. When I was in Israel for a wedding, I tasted the most wonderful aubergine spread - creamy, speckled with a smokey sweetness and depth of flavour, but not rich. I was told that the aubergine had been roasted over a wood fire, like a barbecue.

We cannot reproduce that taste but I have managed something quite close by smearing a little olive oil over the outer skin of the aubergine, sprinkling it with coarse salt and either placing it in a roasting tin, or if you have a gas flame, placing the aubergine directly on the flame to char-grill. Then place in a medium oven for approximately one hour and bake until the aubergine is soft and tender.

Alongside the aubergine I add some halved onions (1 large onion per aubergine), 1 clove garlic and the skins left on. Although some cooks peel the aubergine, I leave it whole. Just remove the stalk and process it with the skinned, roasted onion, the peeled garlic, a 25g, 1oz fresh coriander, a teaspoon of ground cumin and a good tablespoon of tahina for the most gorgeous baba ganoush you will ever taste.

Aubergines are flexible vegetables which combine easily with other vegetables to make satisfying main-course meals.

For a delicious and healthy aubergine and spinach kugel, for four people, peel and slice about 700g, 1½ lbs aubergines. Discard stalk. Cover and simmer in boiling water with a teaspoon of salt for approximately 8 minutes. Wash 450g, 1lb fresh spinach, wilt in the water residue. Stir well. Peel and chop 1 large onion and sweat in 1 dessertspoon olive oil until transparent. Remove, drain and mash the aubergine flesh, chop the spinach adding 1 tablespoon of vegetable stock powder. Leave to cool. Then beat in 3 medium free-range eggs, the onion and 150g, 5½ oz grated cheese - mozzarella, feta, plain cheddar or low-cal cottage cheese, plus freshly chopped chives, basil or a few fresh thyme leaves; season with freshly milled black pepper. Turn into a 1.7 litre, 3 pint dish, top with a handful of pine-nuts and bake in a medium oven Gas mark 3 - 4, 170ºC, 325ºF, for 1 hour or until well set. Serve with mashed potato - baked golden in the oven at the same time.
