Add 1 tbsp sugar and 1 tsp water each in 2 microwave safe ramekins and heat on regular heating mode in a microwave for 3 mins. Make sure to check for the colour after 2 mins and stop and stir in between if required. The sugar should caramelise and become golden brown.
Now, in a bowl, add milk, sugar and custard powder and whisk till there are no lumps. Heat it in a microwave at regular heating mode for 4 minutes. Stop and stir the mixture after each minute to avoid the custard getting burnt or becoming too lumpy.
Pour the custard over the set caramel and refrigerate for at least 4 hours. This recipe makes two caramel puddings.
Carefully demould it by keeping a plate on top of the ramekin and quickly flipping it to release.
