“This is to avoid any possibility of “seething” a kid in the milk of its mother, meaning to cook the meat of one animal in the milk of that animal’s own mother which the Torah tells us is an abomination to G-d. The Talmud then interprets this as a ban on cooking any meat and milk together, or eating such a mixture which is known as basar bechalav – this rules out cheeseburgers and certain candies which may contain both dairy and gelatine – as the rabbis who created the Talmud could find no reason for this rule, it is designated one of the Chukim – those of the 613 Mitzvot (commandments) for which there is no apparent reason…
… Different Jewish communities have adopted different guidelines – most Sephardic (Southern European) Jews will wait six hours, as will many Ashkenazi (Northern European) Jews; but those of German descent traditionally wait just three hours and those of Dutch descent merely one hour. Most rabbis in modern times – including many Orthodox rabbis – favour leniency.”
But look at what Torah says;
“Gen 18:6 And Abraham hastened into the tent unto Sarah, and said, Make ready quickly three measures of fine meal, knead it, and make cakes upon the hearth.
Gen 18:7 And Abraham ran unto the herd, and fetcht a calf tender and good, and gave it unto a young man; and he hasted to dress it.
Gen 18:8 And he took *butter, and *milk, and the *calf which he had dressed, and set it before them (including the pre-incarnate Yahshua); and he stood by them under the tree, and they did eat.”
Looks like Father Abraham needed a Rabbi to give him a copy of the 613 lores
