How many of you have gone out to buy ingredients just to mess around with rather than to eat? It can be a little wasteful but it's great fun.
One time I bought a baking potato and some cod, then sliced the potato paper thin and tried to wrap a square of cod in potato. That bit kind of worked (I par-boiled them obv.). But then the cooking time for potato (oven baked) is far, far greater than that of fish. By the time the fish was perfect (maybe thanks to the potato, it was moister) the potato was still fairly raw. I guess it would be better with pastry.
I once bought an entire jar of apricot jam to try and make an apricot-cream sauce to go with duck. I don't even like sweet with savoury: Epic fail. At least the g/f likes apricot jam.
I have had success with, for example, using a grill pan of water in a hot oven to steam and roast duck that's been "sealed" in a pan.
So, success or failure, what crazy experiments have you performed in your lab?
