I made Lululiz's friend's muffins using more whey! This proves MummyMad's theory that the whey can be substitued for buttermilk, at least in some recipes. Thanks for all your other suggestions too - I found a good ricotta recipe on the net thanks to your advice. Look at the pretty preparations! Thrifted sillicon cases, used for the first time, and a Sarah Smith cleaning cloth sent to me by the great and generous Liz herself.
They made a lovely addition to our tea yesterday - very healthy, very orangey. I substitued loads of things, because we didn't have all the ingredients in our cupboards, and it all worked - farine de blé noir (buckwheat) for wholemeal flour, and raisins and dates for the blueberries. Fresh blueberry season at the farm down the lane will trigger another round of this recipe, I hope.
This funny little photo shows you some of the cheeses from Ben's work canteen - he found they (and other foods) were frequently thrown out so he and several others salvage various bits and pieces at the end of the day! It's not exactly how we would buy cheese but it's free and it's better than seeing it chucked out. I can't eat it because of my low salt requirements, so I carry on with the home-made stuff.
