Do not pretend to know how, but maybe my recipe will be useful to someone. Technology of preparation of such recipes not on the site. As you know, jam products derived uvarivaniem fruit and berries in sugar syrup (honey). Cooking jam should not last more than 20-30 minutes, since a longer cooking deteriorates the quality of the jam unlike jam, berries or fruit boiled to a gelatinous state, and cooked at one time Try my version of Apple jam. Very tasty jam, smeared on the bread, Yes, hot tea :) But this is a matter of taste :)
