Sorry sib, but you gotta buy the spices. They’re like salt and oil, or pots and pans - you are almost always going to be using some of them, no matter what you’re cooking. It helps a lot to find an Indian supermarket, because you can get big packets of spices for much cheaper than the bottles in regular supermarkets.
Also too many spices has never been an issue I’ve had with Jamie, if anything I feel he overrelies on access to good quality ingredients. Yotam Ottolenghi is the spice dickhead, most of his recipes require a specific overpriced spice blend only he sells.
There is wiggle room in baking, but it relies on a deeper understanding of the ingredients than cooking. If a recipe wants 250g of flour and you only have 200g, you have to adjust the amounts of sugars and fats as well, and while the flavourings have a lot more wiggle room, some of them still require swapping out base ingredients for them to maintain the correct ratios.
With cooking if a recipe calls for 500g of potatoes and you only have 300g you can just put 300g in and keep cooking. Recipe calls for 300g tomatoes but you don’t want to waste the last quarter of your 400g can? We’re having an extra tomato-y sauce tonight. You have a lot more room to change ingredients around without it having a significant effect on the rest of the recipe.
