I put the sauce into a tub and left it overnight in the fridge.This morning it has gone thick,very very thick in fact.It looks like a tub of red coconut block.It got me thinking of my take away lesson when I watched the chef cook his tikka massalas.He scooped a big spoonful of red coconut block looking stuff from a tub,melted in in a pan with some oil and just added base sauce and a touch of cream.I got a a good sniff of the finished dish and it smelt just like the one I did last night.
