Andrew's Chinese grandma, Mrs Kok, cooks a mean curry. Her nonya-style food is nice and spicy, and she prides herself on being able to take chilli like a pro.

Grandma Kok may have met her match, though, when it comes to the Subway fast-food chain, Indian-style.

I foolhardily ordered the Paneer Tikka option yesterday - despite the little flaming icon on the board that screamed 'HOT!' - an idea that was perhaps not well thought out.

Paneer is a mild, innocent cheese that I have been wolfing down in quantity since we arrived. 'Excellent!' I reasoned, 'This will be just the thing for my sore, spasming tummy. A little bit of paneer with a touch of tasty tikka treatment.'

No, no, no! When Subway says an item here is hot, they're not kidding! It was by no means unbearable, but it was definitely of the scale where your lips are numb and tingly and your tongue is a distant memory.

Not quite what the doctor ordered. I will take my fast food much more seriously in future.
