Not to everyone's taste, but I use coconut oil instead of conventional cooking oil for most things.
Amazon have a deal on at the moment for 1 litre @ £8.99 (prime members), which is very reasonable.
4 jars from Asda = £6 for 1.2 litres :)
May not be nationwide, seen at Asda in Hayes. Middx
This is the extra virgin type with Medium Chain Triglycerides (MCTs).
Please have a look at an informative HUKD post from BigFishy here
for more about extra virgin coconut oil and it's benefits.
