Honney and Longman,
Yes. I have not tried the piggy cake at all. But I do not really why my husband only loves to eat the 皮.
"淨食皮就得啦,又平喎 "
Yes. this is what I think as well. So easy, no need to buy the salty egg, lotus seed paste etc. Just put a lump of 皮 into the mould and bake and then wait for it to return oil - then he could eat. Then this could be a snack for him already.
