Juan Manuel Lopez Palacios from Costa Rica became the 100,000th member of the portal, which has platforms in 18 countries and 15 languages, in April. He said: “In just one sentence, Rational is consistency, speed and versatility.”

The portal provides chefs with an international recipe databank and tips from chefs and teaching videos.

Vanessa Millard, Rational UK’s marketing executive, said: “Through the Club Rational, our customers have access to ConnectedCooking, the networked kitchen.

“As an international platform, it is a matter of course that we provide our chefs with such services free of charge.”
