Hi JK88,
It’s a bind when you feel obliged to buy ingredients you’ve not had before and they cost considerably more than the stuff we’ve been used to buying. I never wanted to fill my cupboards with loads of exotic ingredients so I picked a few things to try out. Yes, they might be expensive such as coconut oil/flour but they do last – you might not like the smell of frying coconut oil – I didn’t, but I found I can tolerate the smell when I’ve melted it in the microwave so I use it more often.
Coconut flour takes a bit of getting used to since you have to really up the liquids, I don’t think it’s suitable as a general flour substitute, just for certain things.
However, while a kilo bag of chickpea flour is far more expensive than a supermarket’s “value” flour, I’ve really enjoyed the chickpea crackers I make (recipe on this site). So I consider this a good buy.
Almond flour – expensive, but you could probably use ground almonds in baking.
Coconut milk – there seems to be several different brands available – if my Tesco is anything to go by, they have about 4 brands in different places at different prices, so worth burning a few calories to walk round and find one that suits.
You don’t have to buy super-duper expensive extra virgin olive oil – the bog basic olive oil is just as good for you.
Fish sauce – I tried it in a Thai chicken curry which I didn’t really like (possibly too much coconut oil/milk??). But I have used it in soups to give a bit of a savoury touch. When I’ve finished the bottle I won’t buy any more. Likewise, with cacao nibs – expensive and I didn’t like them unless they were roasted to remove the bitterness.
When it comes to fruit & veg, at least we in the UK are in summer (allegedly) so anything seasonal should be cheaper. I’m lucky in that I have a plot at the local allotment – if you have space at home, can you try growing yourself some cherry tomatoes, perhaps? Or grow some favourite herbs, perhaps (they do great on a windowsill). Herbs will add flavour to dishes and keep those taste buds interested.
I guess you have to try these things out but you certainly don’t have to try out everything. When you’ve found things that work for you shopping will become a bit more “streamlined”. But be careful of sticking to just a few recipes – I always find that boredom can have a major impact on whether I stick to a diet so give yourself as much variety as you can. If you try something new and you don’t like it, put it down to experience. I hit Google to see what else I can use these ingredients in to use them up, so they don’t go to waste.
