Well unfortunately I haven't been experiencing that, though for the past two days I've been doing a few each day in the oven.
How the memories flood back with the flavour, not just the open fire, but also the guy that used to sell them fresh from his outdoor oven he would serve them up in small paper bags, that was the treat from your Mum, buying you a bag after she had traipsed you through the Market for what seemed like hours while she stopped and talked for hours to the Market stall holders and of course before she could get to the next stall she would be talking to what seemed like a hundred neighbours, then she would have the cheek to clout you around the ear for dawdling!
But the chestnuts made up for all of that.
