Best Of British By The Sea | Preview (More4)

Whether it's grand facades and afternoon teas, or a bag of chips in the car after a blustery walk on the beach, there's nothing us Brits love more than a trip to the seaside.

In this glorious new series, two of Britain's most-loved foodies - Ainsley Harriott and Grace Dent - explore some of the best seaside holiday destinations and dishes the British Isles has to offer. From local delicacies and cheap eats to high-end dining and fun holiday activities, this is your guide to Britain's splendid seaside at its scrumptious best.

In this episode, Ainsley and Grace start their foodie journey in the stunningly scenic country of Carmarthenshire in Wales, home to long sandy beaches, rolling green hills and incredible flavours from both the land and the sea.

On Llansteffan beach, Grace and Ainsley have a go at the art of cockling with expert Craig Evans. They help to gather the molluscs from just below the surface of the sand at low tide and Craig sets up an impromptu kitchen on the beach to turn their foraged seafood into a delicious meal using more local ingredients, all served in giant oyster shells.

Next, they visit the beautiful town of Laugharne - home to Browns Hotel. Ainsley meets chef head Alex Luck, owner of Dexter's steakhouse, renowned for serving up some of the best steak in the county. At Dexter's, Grace and Ainsley tuck into the aged chateaubriand.

Grace is especially taken by the sides of mac and cheese with beef shin, cream spinach and triple cooked chips; so much so that she doesn't seem to hear a word Ainsley says! At Pendine Sands, on the shores of Carmarthen Bay, Grace and Ainsley take a classic T-Bird car for spin on the famous beach, before heading inland to see rural Wales in lambing season.

They also visit Shadog Livestock Farm, where they volunteer their services for the day. After a long day on the farm, the pair retire to their self-catering accommodation at Cefncilwg, a 17th-century farmhouse in Taliaris. Grace assists Ainsley in making some traditional Welsh comfort food in the form of Welsh Rarebit with leeks, local cheese and pear cider.

And a trip to Wales wouldn't be complete without trying the traditional cawl - a lamb and vegetable stew served with Welsh cheddar cheese - so in Llanddarog, Grace and Ainsley round off their trip with the heart-warming dish.
