Sunniehope, difficult to explain how it looks like. Let me snap a pic and PM u later tonight. My double boiler come in 2 sizes and I bought it many years back. It's a good investment that cost me abt $150. Act there is a base for the chicken to drip in it, but it's v difficult to wash it, so I used the bowl as shown in that link provided by joyhope.
Joynfaith, heard that too but not sure how true. So I don't really eat too much chicken wings.
Actually can use black chicken to make too.
Min81, heard that actually its better to use whole chicken with bones, cos there is calcium from the chicken bones, hence its better to chop it into v small pieces so that can crack the bones and let the bones juice to flow out.
Joy hope, I bought it from hock hua. I just put 4pieces under and inside the bowl.
