I was searching on the web for info on Carlin Sunday -I'm interested in food history and seasonal food and traditions - and this came up (a year late). I come from Yorkshire and we don't celebrate Carlin Sunday, though I'd read the story of a French ship creeping up the Tyne with a cargo of Pigeon peas which saved the besieged population. I'm not sure whether the peas are named after the Sunday (between Mothering and Palm Sundays) or the other way around. When I was looking for food traditions to go with Bonfire Night/Hallowe'en/Diwali (they all cluster around the same time of year) I came across Parched Peas (presumably 'thirsty' peas) from Lancashire, so these peas have at least two traditions associated with them. I saw some a few weeks ago in Holland and Barretts, grown by Hodmedods.
To think that London, or anywhere else for that matter, does not belong to any one demographic
