To Prep
Using a mortar and pestle, grind garlic, black pepper and half of the sliced ginger until a paste is formed. Set aside.
To Cook
Coat a non-stick clay pot with a small amount of cooking oil. Neatly place the uncrushed sliced ginger on the based on the pot and place the celery leaves on top of the sliced ginger.
Using a small mixing bowl, mix sugar, oyster sauce, fish sauce, and soy sauce.
Add the paste from your mortar and pestle into the mixing bowl and mix well.
Add the crab into the mixing bowl, allow to marinate for 10-15 mins, and then remove and set aside.
Drain the glass noodles to get rid of the excess water, then add the glass noodles into the mixing bowl and mix well so they can absorb the sauce evenly.
Place the noodles in your clay pot on top of the ginger and celery leaves. Create a flat top by patting the glass noodles down. Then, neatly lay the crab on top of the glass noodles.
Cook for 15 mins over medium-high heat.
Garnish with celery and serve.
