This was on sale and is something new, so I bought it. They came in a sealed foil plastic tub and bag. There are no instructions on how to prepare them. I googled it and a website said soak them in clean water for 8-12 hrs before use. I did for about 7 hrs and they have expanded a quite a bit, but not completely soften yet. A few blocks were still solid. So I put them in another container and added more water for overnight. Last night, I tried them with coconut milk and tasted OK. If I added some sugar or honey, it might be a bit better. They tasted sour when is plain.
Apparently, according to one website, it said this "真相卻是:植物裡的可溶性膳食纖維是不可消化的碳水化合物完全不屬於膠原蛋白
通俗來說,它們就是帶有大量水分的膠質,被吃下去之後會在腸道內來個單程一日旅行……"
Well, I did went to the bathroom twice this morning! So it's true what the website said. Not the real collegen that we ladies have hope for, just something that helps to clean out the system!
