La Rochelle, Charente-Maritime
‘Nestled amongst the narrow, cobbled streets of the Old Town in La Rochelle is the lively food market which offers a delightful array of delicious local produce. As a coastal town it is unsurprising to discover plenty of fresh seafood, from piles of langoustines to inky black squid on beds of ice. On Wednesdays and Saturdays the market spills out onto the square and the side streets where every inch is taken up by a different stall. One stall expertly lays out a variety of creamy goats cheese in all shapes and sizes. The log shaped ‘Chèvre a la Coupe’ and cone shaped ‘Chabichou du Poitou”‘ are specialities in this region. By the square lies an indoor market hall which dates back to the 19th century, so for generations this market has been the place for locals to meet up and shop.’ By Anika Patel from the La Rochelle-based cookery school Flavours of France.
Also worth mentioning: the covered market on the river at Saintes spreads out into the small street outside the cathedral for a market that is both bustling and charming. Market days are Wednesdays and Saturdays. Royan market has the usual excellent fresh produce, all houses under a dramatic shell-shaped building, a striking example of modernist architecture built during the town’s 1950s reconstruction. The market is open seven days a week from 7am-1pm but it’s best to get there early– before 10am – to see it at its bustling best as locals come to buy not just fresh fruit and vegetables but also the freshest catch of the day.
