How to make canned tomatoes

Big cherries are fruit trees that are not too cold tolerant, and are suitable for cultivation in areas with annual average temperatures of 10-12 degrees Celsius. Abnormal temperature refers to high temperature and low temperature that exceed the temperature range of large cherry. Under normal circumstances, high temperatures have a lesser degree of harm to large cherries, and low temperatures have a greater degree of damage to cherries. (a) Peel the tomatoes and pour boiling water into the micro-boiling hot water for about 1 minute to loosen the cortex, then quickly put people in cold water to cool, peel off the skin, and trim the appearance of the fruit to remove the green or with For other spot parts, then put in a 0.5% calcium chloride solution, dip and harden for about 10 minutes, remove the residue after washing it, and then sort according to the quality standard.
