'Heston's Victorian Feast', the first of four programmes, gave Channel 4 a 9.8% share of the 9-10pm audience and was watched by another 367,000 people on Channel 4+1. The chef will attempt a medieval feast net week.
BBC One's 'Mistresses' won the slot with 4.3m (an 18.5% share), which was 100,000 viewers above its second outing last week.
Next came ITV's cops-with-cameras style fare 'Total Emergency', which depicted the work of all three emergency services in Sheffield and earned 3.1m viewers and a 13.3% share.
Five was close to ITV with 2.9m (12.6%) tuning in to 'CSI', but BBC Two got the slot's smallest terrestrial audience for a Horizon special challenging attitudes about nudity; 1.8m watched giving the channel a 7.6% share.
