We had a lovely salad out in a restaurant on Saturday and they used this dressing - which I assumed was balsamic vinegar (I've never bought it before, so not sure) - it was dark brown and quite thick like an oil and sweet - they also used it as a dip for crusty bread. Anyway, I bought some this morning in Morrisons and it isn't like it at all - this is more like normal vinegar and very runny - have I totally got this wrong and the dressing was something else.
Weird question I know - but I thought there might be a expert out there!
