Jean Rickard spent $400 and 135 hours making 11,000 Christmas cookies this year because her mother never did.

"I think I felt deprived," Rickard said, looking back. "I never in my life had a home-baked birthday cake. Everything was store-bought. I think I bake cookies for the same reason I felt so strongly about PTA meetings when my kids were small. I even went when I was ill because my mother didn't believe in the PTA."

Rickard stopped for a moment, startled by her own revelations. "I never said this to anyone before. Maybe it's why my mother enjoyed my cookies so much in her later years."

The cookie baking marathons started innocently enough 20 years ago when Rickard first married. "I thought, 'Okay, it's Christmas. I want to have cookies and fruit cake.' Even though I didn't like fruit cakes, I thought they went with Christmas." The first year she made 1,500 cookies, which should have been a clue to the future. Most people don't even make 1,500 cookies in a lifetime of baking.

As the mounds of Christmas cookies grew higher each year, so did the number of Rickard's "assistants." For seven years she ran a nursery school for 14 children. Along with her two children, they helped make cookies. When Rickard went back to work in 1968, she lost her assistants, but not her urge to bake cookies and share them. The circle of lucky recipients enlarged from family and friends to include people in her office.

"I did it one year without thinking I was starting something. Just for people who came by the office. Then it seemed like a nice way to say thank you to the people who help us. It started out as a reasonably cheap way to say thank you, but now it's gotten so expensive."

The $400 price tag on this year's cookie supply is $125 above last year's cost. Overall food prices may have risen only slightly more than 10 percent this year, but the cost of some of the ingredients Rickard uses-chocolate, nuts, dried fruits-has quadrupled. And Rickard won't substitute fake chocolate chips for real ones, rum flavoring for rum, margarine for butter

"I use all butter (52 pounds worth) because the cookies taste better. I haven't always done them that way, but over the years I've found they come out better than with margarine."

Rickard admits she has a tiger by the tail. She's one of the many "victims" of her own generosity. People who begin by baking a few cookies for friends, find the friends come to expect them. "Now, after Dec. 1, people in the office start asking.They come from all over the building. Some are regulars. They come every day for three or four weeks. Some of them come with napkins and take a lot of cookies. They always say 'These aren't all for me.' But I've never told anyone, 'That's enough.' It makes me feel good."

Now that Rickard's children have no time to help bake cookies, she has found herself two other assistants: her husband, Ed, and Jill Stanley, an office colleague. Stanley has been helping for the past five years. "Baking cookies is part of her job description, No.989," Rickard kidded.

Rickard's husband, Ed, is the official grinder and Hershey Kiss peeler. "He peeled 10 bags of Hershey Kisses this year," Rickard said, "and he wasn't too happy about that." As grinder he has his work cut out for him: graham crackers, walnuts, pecans, vanilla wafers, apricots. Two years ago he bought an electric grinder. "It didn't work and now it's in the basement," Ed Rickard said. "So I had to go back to the hand grinder."

Last year Ed solved the problem. "He bought me a food processor," Jean explained, but her husband confirmed that he really had his grinding chores in mind when he picked it out.

Rickard bakes 14 different kinds of cookies, plus some cakes and cocktail-type nibbles such as cheese balls and a party mix called Nuts and Bolts. The Mexican Wedding Cakes, cookies made with lots of butter, sugar, flour and finely chopped nuts, are her favorites. They are "the only ones I ever sample when I bake," she said. "I guess I must get sick of looking at the rest of them."

For three weeks, beginning in November, trying to satisfy the cookie monster takes precedence over almost everything else. "It rules our lives and I think it's gotten out of hand, but my kids have always loved it," Rickard said with a sigh. "I start baking at 5, as soon as I get home from work. I never leave the kitchen until mid-night. And then I bake all day every weekend."

As the cookies are finished, they are either stored in airtight containers or put in the freezer. Preparation of dinner tends to get left to fast-food emporiums. Invitations to Redskine games are turned down. She uninvited her sister for Thanksgiving dinner because the sister planned to bring a friend and Rickard didn't want to clean up or set the table.

She admits there was additional pressure on her this year several parties including a large cocktail-buffet in honor of her father, former West Point football great Harvery "Jabo" Jablonsky, who recently was elected to the College Football Hall of Fame.

Every year Rickard swears she'll slack off. Her husband doesn't believe it for a minute. "She'll never stop. She enjoys it too much." Rickard agrees. "I shouldn't knock it. I do love it. Besides, people depend on these cookies."
