Or rather, extremely commonplace things I can't easily find in the UK.
Yes, that's correct. For the last four months I've been on the hunt for white vinegar. Thinking maybe it was called something different here, I actually went online, found a picture of white vinegar, and sent it to a friend asking where I could find it here. She asked if I meant white wine vinegar, which of course, I did not. I meant, you know, plain white vinegar of the caliber you use to clean your coffee maker. In fact, that's why I wanted it! Well, after much searching, I found some. At the vegan grocery store down the road. In the cleaning products section. For a ridiculous price. And, I bought it. Now, I have a sparkling white coffee maker, and I'm so happy.
On to yellow squash, another item I looked for today. I couldn't find it on my online shopping website, and, admittedly, I didn't look very hard elsewhere. I did ask a friend if it was called something different here. (Coincidentally, I asked the same friend I asked about the white vinegar. She's very patient with me sending her random pictures asking if what things are called here.) Apparently, yellow squash is a yellow courgette (zucchini), but it doesn't matter. She informed me that you really can't find them in stores. I'd have to know someone who grows them. I don't usually like yellow squash, so really it doesn't bother me that I've had a hard time finding it. But, it's the principle that matters! I needed it for a recipe. Instead, I'll be substituting eggplant (aubergine) for yellow squash. The horror!
