Pumpkins are now appearing to proclaim the arrival of Halloween, but as the seasons change, Tesco continues with its campaign to inspire shoppers with fresh produce ideas.

This is taking many forms, including photos of produce and recipe ideas, linking suitability with associated grocery lines. Lemons are recommended for three meat dishes and clementines for a pudding cake and Pavlova. The chain also continues to popularise lesser-known vegetables.

This week it’s chard, offering a British grown, Big Leaf pack at £1 per 300g in a red and blue-labelled poly bag.

More unusually ‘Subtly pink’ onions, in a similarly coloured net at £1.30 for three, are being promoted in aid of Cancer Research UK.

Children have always been natural targets when it comes to fruit, and Sainsbury’s is wooing customers with mini easy peelers endorsed by Mickey Mouse and a chance to obtain a free backpack by collecting 20 stickers off the fruit. The £1.75 for 10 are Clemgolds grown in South Africa. Nearer to home there are kiwiberries from Italy at £2.75 per 125g.

Dragon fruit has so far mainly been sourced from the Middle and Far East, but at Morrison’s a crop is now arriving from Kenya at £2 each. It has also elevated the humble beetroot with a raw Candy variety grown in France at £3.99kg and bumpy RAF tomatoes from Spain at £3.49 kg.

Butternut squash continues to grow in popularity, arriving in both whole and in a variety of semi-prepared chunks with other stew-pack root vegetables, suitable for everything from the summer barbecue to the winter roast Sunday lunch. Marks and Spencer has now added a new scooped-out half version at £1.69 to its fresh-cut range.
