Hello, I'm a chef. There are many ways to cook this dish. I will give you a simple one. To cook this dish, you must have a pressure cooker, two maltose and half a can of honey. The ratio is one spoonful of water, two spoonfuls of sugar, then half a tube of honey and two maltose. This is the ratio. See if you burn more or less yam. Put white water in the pressure cooker first, then sugar, then maltose. Put the cooked pressure cooker on medium fire 10 minutes, then pat it with your hand. Thank you. I'm glad to answer this question for you. This dish is called high fever yam, not high mountain yam.
