2. Put the crushed Colla Corii Asini into a container that can be covered with a lid (the kind of microwaveable bowl can be used, remember to have a bigger bowl, we will have to clip a lot of things into it later), pour in 500ml of yellow wine and soak for 2-3 days. The soaking process is still quite long, we do not rush, slowly let it soak it, soak a 3, 5 days are no matter. Besides, we have other things to do in this process.
3, in this 3, 5 days time we can prepare other ingredients.
If you have the conditions, you can fry the walnuts, and then use a blender to beat into very small particles, if you do not want to fry, it does not matter, directly to the raw walnuts into the blender to beat into small particles. It's not necessary to grind the walnuts into a fine powder, I think it's more chewy to grind them into small grains. The following is to fry sesame seeds and grind them in a blender, or go directly to the supermarket to buy ground cooked sesame seeds, now the general supermarkets have to buy, but the price is slightly higher, about 10-11 yuan / half a catty. It is best to buy kernel-free jujube, if there is a kernel, then remove the kernel first, and then put the jujube into the blender and beat it into a thick shape.
4, three or five days later, the gum probably also soaked well, the original fine block becomes thick. Prepare a relatively large iron basin, the rock sugar 250g, will be ground sesame powder, walnuts and red dates, as well as wine and Colla Corii Asini together put in. Use chopsticks or a big spoon to mix well, and then put a lid on the iron pot, preferably not into the steam, so that it can be left for a long time, and will not be easy to mold. Put it in a steamer pot over water and steam for 15 minutes on high heat, remember to make sure it's on high heat, during which it's best to turn off the heat, wait for the steam to come down, open the lid of the pot inside, and then use chopsticks to stir, and then re-cover the lid and steam on low heat for 2-3 hours. When it's hot, pour the steamed paste into a four-square box (I use Locklock box, it's better to store it in the fridge) and wait until it cools down, it will naturally solidify into four-square paste. Then use a knife to cut it into almost equal pieces (each piece weighs about 10 grams), each time you eat 1-2 small pieces, so it is better to take, and very hygienic Oh. I have heard that as long as it is properly refrigerated, it will not spoil for most of the year.
