Tub Tim Grub (Crunchy Rubies)

The blog is definitely overdue another Thai dessert, it’s nothing personal, it’s just I’m a bigger fan of savoury than sweet. However, we’ve been having some warm days lately so a cool and crunchy pudding seemed in order and this dessert was one I’ve been meaning to get round to for ages- it’s a really popular well known hot weather dish in Thailand.
‘Tub tim’ can mean either rubies or pomegranate in Thai- it’s easy to see why this dish shares that name. The cool, sweet coconut milk is an awesome contrast to the jelly coated crunchy water chestnuts.
I only had tinned water chestnuts and coconut milk available to me but if you can get fresh, I would definitely use them.
For two people use:

• a handful (roughly 12) peeled water chestnuts- note: if using canned, drain and leave them to soak in fresh water for 12 hours, changing the water over several times to reduce the ‘tinned’ flavour. Cut each chestnut into 4 equal bits
• 1 cup of tapioca flour
• half a can of coconut milk (200ml)
• 100ml of water
• a teaspoon of red food colouring, mixed with a small splash of water
• a tablespoon of sugar
• crushed ice

Put the water chestnut pieces into a bowl with the red food colouring and water. Turn them gently and leave them to soak for 15 minutes.
Get a pan of water boiling
Drain the water chestnuts of excess colouring and put them in another bowl with the tapioca flour and coat them well.
Shake off the excess flour and gently lower them into the boiling water- you’ll see the bright red colour become visible. After just two minutes, they’ll float to the surface. Use a strainer to scoop them gently out and transfer into a bowl of very cold water for a minute.
Dissolve the sugar in the 100ml water and add the coconut milk and crushed ice. Pour into serving bowls.
Scoop the ‘rubies’ out of the cold water, gently shaking off the water and divide amongst the coconut milk.
