M&S Food has revealed a series of sweet, summery dips as dessert options for a 'picky tea' ahead of National Picky Bits Day this SaturdayIt also comes as the UK basks in the sun amid a heatwave which is predicted to break the record for June temperatures - and, according to M&S, this may drive up demand for a 'picky' meal at dinner time.In April the retailer released research which suggested 43 per cent of Britons indulged in a 'picky tea' once a week during the summer as they desire lighter meals.These meals might include crisps and dips, fresh crudites, savoury pastry bits and charcuterie.More than 70 per cent of the retailer's customers said cheese and crisps are key elements of the 'picky tea'. But the supermarket also aims to cater for all traditional 'courses' including dessert with its new dips, hoping to provide a sweet ending.As the sweet sandwich takes to the shelves, it's surely set to divide shoppers for another summer. In addition to M&S's Strawberry & Creme Sandwich, the supermarket has introduced a Chocolate Strawberry and Pistachio Creme Sandwich for those with an extra sweet tooth The Red Diamond Strawberry & Creme sandwich is returning to M&S shelves this season - just in time for WimbledonThe product was first introduced last summer and is filled with fruit and lightly whipped cream cheese, served on fluffy sweetened bread. It is inspired by Japanese 'sweet sandos', also known as fruit sandwiches.Japanese sweet sandos originated when fruit shops opened near major train stations and business districts in the early 20th century.As these businesses grew, many began to open cafes to allow the public to access luxury fruits at a reasonable price by incorporating them into dishes such as parfaits, shortcakes and sandwiches.To appeal to British audiences, the retailer opted for the classic strawberries and cream, which has long been associated with the Wimbledon Championships. The retailer has also introduced the Chocolate & Pistachio dip as an even sweeter option in its picky bits rangeThe snack's origins at the tournament date back to the late 19th century when British strawberries were considered a luxury item for upper-class spectators to eat. As the fruit reaches peak ripeness in late June/early July, it was harvested quickly for consumers to eat there and then, before it became overripe. Upon the launch of the sandwich last year, shoppers posted their verdicts of the sandwich on social media.One person rated it a '100000/10' and said it was the 'best sandwich ever' while commenting on M&S' Instagram account. The Daily Mail's taste test of the sandwich determined it was 'more like a dessert than a sarnie' and gave the product three out of five stars.However, the cream cheese-based filling divided some customers who felt the sandwich was not as sweet as they'd imagined it to be.But M&S reckons it has the answer for those sweet-toothed shoppers; in the form of its Chocolate, Strawberry and Pistachio Sandwich.The new product made from sweetened bread that has been enriched with cocoa and is filled with a layer of pistachio creme, Fairtrade Belgian dark chocolate sauce and sliced British strawberries.
