    Worked out perfectly and was delicious. Kept well in the fridge.

    I’m trying to work out how I measure 250 grams of olive oil. Why not spoonfuls or cup measure.

    Thermo Foodie and The Chef says:

    Hi Liz, thanks for your message, you put a cup on top of the thermomix and turn on the scales then weigh the oil into the cup. 250g oil is the same as 264ml. We dont use cups because an Australian cup is different to a US cup and we dont know where our followers are dialling in from 🙂 Where in the world do you live? We live in Perth, Western Australia
