I can't remember whether it was in Greece or Turkey that I first tasted Halva - an Arabic/Middle Eastern confection made from tahini (sesame). It tends to be eaten with a cup of coffee rather than having a biscuit, but I also recall seeing it at some hotels in Turkey served on the 'help yourself buffet table' at breakfast time. It is delicious but the flavour and texture are both difficult to describe, and although it is a confection it is not overly sweet. The Halva I like is filled with nuts - pistachio or almonds, but it comes in many different flavours.
I had been unable to track it down in the UK, that is, until I noticed that Lidl were having a "Greek Week" and there on the shelves blocks of Halva appeared. They had three types: chocolate flavoured, Macedonian honey, and roasted almonds. I noticed that they still have some blocks left this week as I suspect that many people do not know what it is. I am just enjoying the last slice of halva with a cup of coffee, but will be watching out for it again during their next "Greek Week".
p.s By the way I am not in cohoots with Lidl
