Large Tesco sells Rapeseed oil (from Belgium) at £1.30 per litre but it looks like the diluted version i.e. the colour is much more lighter and the flavour rather neutral.
Well apparently Rapeseed oil has a higher heating point compare to other oil.
I also have the expensive ones at £3 per 300ml and the colour is thicker and the flavour is apparent. Depending on what you are cooking the stronger flavour might or might not impaired the taste.
I am Sunflower oil person but been trying the £1.30 Belgium Rapeseed oil to see what the fuss is all about and also the £3/300ml expensive ones …
