Place silken tofu in a mesh strainer over a mixing bowl and mash the tofu with the back of a spoon. You will have smoothly mashed tofu in a bowl.
In another small bowl, beat eggs. Sieve the beaten eggs through the strainer as well.
Add chicken stock to tofu and egg mixture and mix well. If using salted shrimps, finely mince them and add in to the mixture or use salt. Add green onions and sesame seeds to the mixture and combine everything.
Divide the mixture into 2-4 microwave-safe serving bowls and cover with plates (microwave-safe) on top.
Heat the mixture on a high power setting in a microwave; 6-8 minutes for 2 bowls or 3-5 minutes for 4 bowls.
When done, the pudding will be very hot so be very cautious. Serve hot.
