I spend easily, and on anything!
However for some odd reason I HATE to buy lemons - they are so expensive to buy and so many people have trees and too many lemons!
I always have some juice in the fridge (bought not home made) that I use occasionally however have noticed I am using it more lately as lemons seem to be scarce and indeed last time they had been imported from U.S. which I find strange!
I love salmon fillets, Jonaj, we eat them once a week. The lemons? I buy them for my G&T to use over fish, & in recipes. IF I happen to have run out before I do my next shop, I'll use the not nice stuff in the little plastic bottle, which I keep in the fridge as a last report! I suppose it's better than nothing!
I prefer fresh, especially on pancakes, however I do usually have a little bottle in the fridge "in case". I agree with others here that the bottled stuff tastes odd. I prefer berri over the cheaper ones but it seems to be disappearing from my supermarket.
I use fresh lemons or limes. I have some trees, which haven't cropped well lately. I have never bought the fake juice. I see my sister uses it and she is a very good cook, so maybe it has improved, since my days flatting with people. I would rather spend money on fresh fruit that buy other items.
