In a pan dry roast the perilla seeds untill it starts to crackle and you get a nice aroma. Remove from heat.
Add them onto a mortar and pestle and pound them into a coarsely powder.
In a mortar and pestle add in the roughly chopped ginger and garlic. Pound them coarsely just to open the flavor.
In a heavy bottom pan add in the pork.
Add in salt, local chilli powder and raja mircha (king chilli) if using.
Stir and mix well. Put on the lid and cook in low-medium flame for about 10-15 minutes stirring occasionally in between the cooking.
The pork will start releasing its fats and it will get cooked on its fats.
Add in the fermented bamboo shoot extract and the pounded perilla seeds. Give it a good mix.
Now add in some water. Put on the lid and cook further untill the pork is tender and cooked well.
Cooking time depends on the tenderness of your meat. It took approximately 45 minutes to 1 hour for me.
Add in the ground ginger and garlic. Mix well and cook for 2-3 minutes.
Turn off the heat and finally add in the roasted sichuan peppercorns by crushing it in your palm. Mix well.
Your pork with perilla seeds is ready to be served. Enjoy wih piping hot steam rice.
