Ha, maybe it's not a Bolton thing, maybe it's a me looking in the wrong places thing. Where would they be, with the bread flours and yeasts? In the home baking section? In the world foods section? Actually, I did try that approach recently. I saw a Nigel Slater recipe that called for preserved lemons. Checked it out online and found that Sainsbury's had them. Went into Sainsbury's, couldn't find them, asked someone, and was led to a completely different place than where I had looked, to find the jar looking exactly like the image I had seen online. I suppose that what I need is a big flashing red light over the specific ingredient I am looking for. Still, I'm certain that the supermarkets really don't stock rose veal. Too costly to sell well, I suppose.
