Just for reference:
ASDA lard costs 0,39 for 250g.
ASDA cheapest oil is 1,09 for 1l.
Even that cheap oil is going to be more versatile than the lard, as it won't impart...shall we say, unwanted flavours while frying. You could also use it baking muffins, which are usually made with oil not butter. Plus, as cooking fats are usually substituted 1:1, the oil works out cheaper in the long term...
...and IT'S NOT bleeping LARD.
(yes, I know Jack always claims that she's thinking of people who only have 39p, not 1,09, but in that case, put the manky sugary cereal bars and assorted maize snacks back, no?)
