A local Asian supermarket used to sell this stuff that the proprietor referred to as dried tofu. In came vacuum packed, and seemed to be dehydrated tofu that had been marinated in Chinese barbecue or chili sauce. It was soft, but slightly chewy, and totally delicious.
That closed down, but by happy coincidence I switched jobs and had a colleague with a Chinese wife. They would buy this stuff on visits to China, in an even wider variety of flavours, and were happy to bring me some back when I asked.
I've now moved on. I've been searching the other local Asian markets for this snack without success - indeed most staff in the shops seem visibly confused when I ask for "dried tofu", as though they have no idea what it might be.
Searching online for "dried tofu" turns up a variety of products that are obviously meant for cooking: unflavoured blocks or strips of tofu that need seasoning or rehydrating before use. This isn't what I'm after at all.
"Flavoured dried tofu" doesn't bring up much different either.
This made me wonder if this stuff has a different name other than the "dried tofu" I was given? And whether anyone knew of anywhere I could order it online for UK delivery?
