I finally quick blanch the cockles that I bought for my girls to observe yesterday! I did ask my friend on how to blanch it and she told me – the best is to pour hot boiling water over it, which I tried! This is after soaking and rinsing the cockles few rounds!
The best match is still the sweet and sour chili sauce. The ingredients which I blended with are 4 red chili, 1/2 tsp salt, 2 tbsp brown sugar, 3 cloves garlic and 2 tbsp distilled vinegar.
