In order to be sure of the usefulness of Manchurian nut jam, you should carefully follow the recipe for its preparation.
There are several recipes for Manchu nut jam, but the simplest is to make unpeeled green nuts. To prepare it you will need:
- 100 pieces of milk-ripened Manchu nuts, not peeled;
- 2 kg of sugar;
- 1 lemon;
- various spices and herbs in powder form (ginger, cardamom, cloves, chicory) about one pinch each;
- vanilla extract (sugar or pod);
- about 2.4 liters of water (2 liters for cooking and 2 glasses for making syrup);
- 1 pack of baking soda
If desired, you can add various berries or orange peels to these ingredients.
Manchu nut jam recipe
It takes a lot of time to properly prepare jam from the fruit of the Manchu tree. It only takes about two weeks to prepare the nuts for cooking in syrup. And the process of making the jam itself takes 3 days.
The process of making jam begins with the selection and cleaning of fruits from debris. Then they are poured until completely covered with cold water and left to soak for a day. During this time, the water should be changed at least three to four times, while the nuts should be washed under running water.
Warning! After soaking these fruits, water acquires an iodine smell and color, so it is not recommended to pour it into the sink or other plumbing, so as not to stain the surface.
After soaking the fruits in ordinary water, they are pierced or punctured, and poured with a special soda solution (5 liters of water are mixed with 100 g of soda). The nuts should be in this solution for about two days, then it should be changed. The procedure is performed 4 times. In this case, the nuts must be mixed as often as possible. This procedure is necessary to get rid of the bitterness of the fruit.
After the walnut fruits have been soaked, they are removed and dried for the next cooking in syrup.
The syrup is made from sugar and water.
Dissolve 2 kg of sugar in two glasses of water and put on high heat, bring to a boil, removing the white foam. Reduce the heat and dip the soaked and dried fruits in the syrup. Together with the nuts, spicy powders are added, as well as finely chopped lemon. Bring to a boil again and remove from heat. The resulting jam should be infused for at least 24 hours, then it is put on the fire again, brought to a boil and removed for infusion.
In total, the jam should be boiled at least three times, until all the water has boiled away and the jam acquires a viscous consistency, reminiscent of honey.
For aroma and piquancy, vanillin is added to the finished jam before the last removal from the stove. It removes the tart nutty odor.
The resulting jam is poured into jars, which are sterilized in advance and tightly closed with a lid. To seal the jars, the jam should be poured hot.
Advice! To diversify the taste of this jam, you can add garden and forest berries to it, or use citric acid with the addition of orange peel instead of lemon.
