Yet another of magazinedom's terrible voids has been filled: Kosher Home is about to begin publication.

With guaranteed half-a-million circulation culled mainly from synagogue mailing lists, Kosher Home is intended for those Jews who observe the dietary laws. "There is no magazine for those people, they need a magazine," says publisher Larry Rubin a bit messianically. "We're filling in that gap."

Although he admits that when advertisers are approached about Kosher Home and such articles as "Kosher Touring in Palma de Mallorca," "their first reaction is to laugh. But once they hear what a unique advertising concept it is, they become very receptive. Did you know that there are 10,000 products certified as Kosher, that three-quarters of our audience maintains four sets of dishes? That industry is very interested in our publication."

And does publisher Rubin keep Kosher himself, does he observe the traditional separation of milk and meat? "I'm a vegeterian," he replies, and that appears to be that. My Lips Are Sealed

If you're tired of the New Morality, you can relax because the Old Morality is about to become the New New Morality, leaving the erstwhile New Morality feeling very tacky indeed. For instance:

"The fact that I'm not living with a man really drives some people crazy," says Debby Boone, Pat's daughter, in "The Case for Virginity" in the June Redbook. "I don't want to be a woman who's given herself away, a drib here, a drab there, until she's much less than whole."

Over in the June Ladies' Home Journal, Charlie's and apparently real-life Angel Jaclyn Smith, star of the forthcoming TV movie "The Users," says she hasn't read the racy tome it's based on and doesn't plan to either because "I don't read dirty books. After 10 pages, they're all boring." More than that, the actress says, "I would never have taken the part if it were a feature film with all the language and the nude scenes that would have been required. Not in a million years."

And finally, Barbara Cartland, the Queen of Romance Novelists, appears in the pages of the June Forum to say, "I am convinced that kissing, like 'making love,' should be an expression of sincere affection, but I suspect that the over-kissing we have to endure is really just part of the lack of self-control which appears in every walk of life."

Maybe it's a trend. The Big Questions

"Profound questions of our age," New York feels, have as much right to be answered as any others, so the May 15 issue of the magazine tackles the following all-time puzzlers.

How fast is a snail's pace? About two inches per minute.

How far is it from the Halls of Montezuma to the Shores of Tripoli? Approximately 6,500 miles.

How fast do hot cakes sell? The Insternational House of Pancakes sells 3,264,000-plus in a year.

How quick is a wink? Between .1 and .28 seconds.

How many coals are there in Newcastle? In 1977, 14,900,00 tons were mined.

How many pickled peppers in a peck? Between 144 and 160.

At what point will the straw break the camel's back? The one added after 1,904 pounds.

If one is worth one's weight in gold, how much is one worth? A 150-pound person in worth $408,000 in gold, $11,930 in silver and about $480 in Bumble Bee solid white tuna. Personal Glimpses

"Do you know when I came to Hollywood they tried to cover it up? I got so annoyed. They covered it all up with putty. And do you want to know something? When you cover this up you have no idea what the size of my chin is. You see, it breaks up the chin. Otherwise I have the biggest chin in the world. Finally it annoyed me. I said, 'What is this crap? For God's sake, I'm not a good-looking guy. This is what I am.' And that was the end of it." - Kirk Douglas on his dimple in Andy Warhol's Interview.

"When I first saw Hitler, with that little mustache, I thought he was copying me, taking advantage of my success. I was that egotistical." - Charlie Chaplin, quoted in Lillian Ross' memoir in the May 22 New Yorker. Wayne's Back!

You can take the man out of politics, but not politics out of the man. Or so the May 29 People would have you believe, revealing that Wayne Hays, 67, late of the House of Representatives, is back on the campaign trail, pressing the flesh for a chance to sit in the lofty precincts of the Ohio state legislature.

When he first arrived back in Ohio after his fall from grace. Hays spent a lot of time down at the post office, weeding out hate mail that would have upset his wife. He then tried a spin at a bank he's chairman of, only to find that he was (no kidding) "a sucker for a sob story." Tired of noticing that "most of the men who were retired were dead or looked 10 years older within a year" and upset by a series of accidents, including a concussion when he was charged by one of his own bulls, Hays decided only politics could save him.

But can he still get out the vote? People thinks so, noting that a stalwart member of the Belmot Ladies Democratic Club recently vowed she would vote for Hays forever because "he got the water out of my basement. It stood there for six years before I wrote to Wayne Hayes." Numbers Racket

The Audit Bureau of Circulation figures for the top-selling magazines of the second six month of 1977 have just been released, and the winners are:

The only change in the top 10 was the National Enquirer's move, courtesy of a nearly 200,000 jump in circulation, from No. 10 to No. 9. In fact, it was a fine six months for all publications of the Enquirer's ilk, with The Star gaining 800,000 readers and moving from No. 23 to No. 16, Midnight Globe gaining 250,000 and moving from No. 39 to No. 31, and even True Story picking up 250,000 and going from No. 36 to No. 26.

One sad note for clean-livers: Scouting lost 100,000 readers and fell from No. 48 to No. 53. Thus pass, etc., etc. Tidbits

Cover line of the month is from the Official UFO magazine issue on Ancient Astronauts and reads, "Strange Hybrid Clones: From Alien-Human Intercouse." . . . Free Enterprise magazine reports that the seller of the very first McDonald's hamburger was one Arthur C. Bender, a counterman at the company's opening stand in San Bernardino, Calif., in 1948. X-billion burgers later he's a millionaire.

Potomac Journal, a new monthly magazine that hopes to cover local government in the District, Maryland and Virginia like a blanket has set up shop at 711 E St. SE. "While our focus is serious, our style will be sassy and irdeverent," says the editor. Here's hoping . . . Equus magazine out of Gaithersburg has tripled its circulation guarantee from 50,000 to 150,000 in six months . . . Ladies Homes Journal reports that normally mild-mannered Woody Allen considered shooting inquiring photographer Ron Galells with a BB gun to keep him from snooping around the set of his sacrosanct new film. And to all a good night.
