Low fat red ruby milk pudding using agar agar
Low fat red ruby milk pudding

This traditional and well-known Thai dessert is famous in most Thai restaurants. Not to mention that this is one of my family’s favourite dessert too. We like to finish our course of a meal with either Mango sticky rice or Red ruby.

One of the main ingredients in this recipe is coconut milk. The coconut milk gives the nice fresh sweet taste to this recipe.

I am making this recipe using milk instead of coconut milk to make it healthier and low-fat recipe. I am using agar-agar to make this red ruby into a pudding.

Tub Tim Krob or Thapthim krop is a Thai name for the Red ruby we are planning to make.

What is red ruby milk pudding dessert made of?

Water chestnut

A Chinese staple vegetable prominently used in Chinese cooking. A vegetable looks like a chestnut in colour and shape. But it has nothing to do with chestnut. This is an aquatic tuber vegetable that grows in water.

Food colour

Red food colour or any natural red colour will work in this recipe. The outcome of red rubies on white background can be achieved through good quality food colour or natural red colour from any food.

Tapioca flour

Store-bought tapioca flour works fine for this recipe.


The regular low-fat milk is the dairy I am using in this recipe.You can opt for full cream milk if you wish so for a creamy texture.


Raw sugar is the sweetner I am using here.You can add any colourless sugar or sweetener to retain the white colour.

Pandan leaves

These aromatic leaves gives mild flavour to the pudding.These pandan


An alternative to gelatine,I am using agar-agar to make a jelly like substance.
