What, if any, is the consensus regarding rye flour amongst the aficionados? I've often used it as a lesser ingredient with white & wholemeal, typically 200g white, 150g wholemeal, 50g white, but at those ratios you hardly notice that it is there. I notice that Marriages have rye flour at under £13 for 16kg. I don't want to buy a load of stuff I can't use before its best-before date though.
