I currently use sunflower oil and the results are disappointing. With the roast potatoes, I parboil the potatoes for 5 minutes, shake them to rough up the edges and then add to hot sunflower oil on a tray in the oven. There is always an after taste which I personally find unpleasant.
With yorkshire puddings, they just don't rise enough (I use 100g plain flour, pinch of salt, one egg and half pint of skimmed milk). Is this due to the sunflower oil not being hot enough even though the oven is set to 220 C?
Any advice/tips will be appreciated.
Thanks
