Not particularly christmassy, BUT....
during my escape from the care system into normal living, I was in (Irish carlsberg, make the...) the crappiest bedsit I've ever lived in (and I've lived in some pretty cheap shit places).
I was soo poor (no seriously. Not like today, where they give you a flat, kit it out, and give you hundreds for having lived in care. Back then you got jack shit) that I used THIS recipe, I called it the GUT BUSTER
it's so easy to follow...
Add an amount (any amount) of plain flour, an amount of sugar n butter (or that pretend plastic stuff... Check your ingredients against paint!) And mix. If ya lucky n got sultanas etc chuck some in, and if ya got it a sprinkle of cinnamon etc for taste.
Then add as much milk as you can spare to change from crumbs to paste/pastry like consistency.
Use some oil to grease a baking tray (or one of the teflon things)
Now spread out the mix, until approx 1cm/½” thick
Sprinkle a small amount of sugar on top.
Place in the oven on gas 5/170C for approx 25 mins (keep an eye on it, as depending on quantities used can cook quicker or even burn.
Once cooked, remove from oven, and place on cooling rack.
It's ok tasting, but fills you up when you're really hungry, and got nothing else to eat.
You'd never guess from that, that I was an industrial chef for quite a few years (industrial... Large canteens, hospitals, that sort of size cooking). Mind, it took me a couple trys to make 40 gallons of custard without lumps! lol
Typo now corrected.
