Kaz the 99p shop has soda crystals, I use half the dose of washing powder/liquid and add a bit to the wash
And the plugholes too
I have some frozen garlic mushrooms Ossie
They were bought from Lidl for 30p a bag when they flogged off leftover Christmas stuff. We had some at Christmas for our bits and pieces buffet and the boys loved them, so they'll get used eventually. Dreadful things, big parcels of breadcrumbs with a tiddly mushroom inside - in fairness of course the mushrooms are quite big till they're cooked
Frozen sliced peppers are something I usually have, they're often a lot cheaper than fresh and handy to have. But at the moment, neither Morrisons nor Waitrose have them, it must be a seasonal supply thing
