Can I use any other oil rather than vegetable oil in the Yogurt Pot Cake, as husband cannot eat it. I wondered if I could use olive oil instead?
Nigella's Yogurt Pot Cake (from NIGELLISSIMA) is made with vegetable oil as this is flavourless and won't interfere with the vanilla and lemon flavours of the cake. Vegetable oil is usually rapeseed (canola) oil in the UK and soybean oil in the US. If your husband is unable to eat one of these then you could another flavourless oil instead. Our preference would be for sunflower oil, but corn or peanut (groundnut) oil could also be used as alternatives if your husband can eat any of these. Safflower oil is another alternative, but tends to be expensive.
Regular and extra virgin olive oils are strong in flavour and this would come through in the cake and mask the other flavourings. You could use a "light and mild" olive oil, which is a more refined version of olive oil. It is lighter in colour and milder in taste so should not affect the flavour of the cake so much. However this type of oil can vary as often some extra virgin olive oil is added to the refined oil mixture, so our preference would be, if possible, to use one of the flavourless oils mentioned above.
