Sauces

Gregg Wallace is in the Netherlands at one of the world's biggest sauce factories. Its annual output is a quarter of a million tonnes of condiments, and more than 50 per cent of this heads to the UK. Our passion for sauces sees us consume 40 million kilos of mayonnaise every year. Gregg follows its production from a farm near Arnhem, where 23,000 free range hens produce the eggs, to the factory, where he is wowed by an egg cracking machine that can separate the yolks and whites from 1,700 eggs a minute. Meanwhile, Cherry Healey is making the glass jars Gregg needs for his mayonnaise.
