For me, a recipe is just a guide, I think oh that sounds nice, then hmm I dont have that or that, substitute or omit and see how it turns out :)
Re the yoghurt - I make my own, a couple of kilo every week using 4litres of UHT skimmed milk from Lidl - £2.64 I use a ninja foodi 15 in 1, which was expensive, but it earns its place here as a yoghurt maker, bread maker, pressure cooker, slow cooker, as well as the roasting and air frying functions
We gave up growing veg. We live in NI and only have a tiny window of growing weather and the time and money wasted over the years - we gave up. I do grow Sage, thyme, rosemary, chives, and bay - cos they just come back year in year out
For me our meals are based around whats on special offer or whats been reduced . I dont have a weekly budget, because when legs of lamb and joints are half priced, I buy a few of each for the freezer. Legs are cut in half, with the leg meat from the knuckle end used for other dishes. Large joints are portioned into smaller sized ones. Lidl do chicken breast portions - badly cut fillets - they look like a fillet but the tops might be cut wrong - and they are usually a pound or more cheaper for KG. They are huge and I seriously can use just one to feed three of us ( in a chinese meal like chicken and black beans )
Rice I buy by the sack - 10kgs, does about a year. Pasta, that too is bought in the biggest bag I can find. And I dont be bothered about different shapes for different dishes, bolognaise is the same on penne as it is spaghetti :)
Lentils are your friend. Huge punch of protein for very little cost and cook into a bolognaise , you can halve the meat content. HM dhals are so filling , cheap and easy. Big pots of ham and lentil soup ( I buy a ham hock for £3, boil that up, use the stock for the lentils, take the meat off the bone, use some for sandwiches, some in a quiche and the rest into the soup ) - three different dishes of 4 or more portions - £3
Another trick I have, here at christmas especially, there are always huge packs of cocktail sausages reduced - like 80 for £2, I buy loads, split them up into small bags and they are great in a sausage casserole, into toad in the hole or even as a plate filler with a chicken dinner, and always handy for the grandkids. Usually I do a bread stuffing but at christmas, if theres the nice posh flavour ones reduced - I stock up on those as well
As a scratch cook I do have a huge array of spices and herbs, but only the ones we use most - we cook a lot of chinese and indian style dishes, so always soy sauces, rice wine, sesame oil, along with tumeric, cumin and coriander. When I get to the UK I always hit the chinese supermarkets for stuff like fermented black beans, dried mushrooms etc, the bits that we cant get here or they are ridiculously expensive. And stock pots - I do love the red wine ones ( cheaper then opening a bottle ). For general soup stock, the polish vegetable seasoning in a blue bag for 85p ( often 2 for £1) is superb
We are meat eaters but I do cut the meat and double the veg content as much as I can. Frozen veg is great save. They were looking £1.10p a cauli at easter and I needed 2. I got a kilo of frozen florets for £1.35, made a huge dish of cauliflower cheese that did 8 generous portions and Ive still some florets in the freezer. Stew mix - bargain, that and a pack of stewing beef, a stock cube, in the pressure cooker - 40 mins later dinner is ready
