Obviously it needs to go in the fridge otherwise it could ferment and become rather interesting.
I suppose I could buy some more puri and take them and it to work, since we are going back to Leicester where I bought it tomorrow. It took great effort to get to the shop since there is a little known law that every year one British city must be moved 3 feet to the left or to the right, and this year it is Leicester's turn, which means there are an insane number of roadworks going on simultaneously. A less deranged person than I would have given up and come home and got a take-away here, but I reached the state of mind where I was damn well going to find somewhere to park and go to the shops I intended to go to come hell or high water.
I suspect that this has also solved another mystery which is why do things you make with tamarind never taste the same as stuff in restaurants, I think the answer is that the sauces in restaurants have a mixture of tamarind and dates as their base, and that tamarind on its own has a rather flat flavour.
