Next Monday evening marks the beginning of Rosh Hashanah - the New Year festival celebrated by Jews throughout the world. Unlike Passover, where bitter foods are prepared in commemoration of hard times, the Rosh Hashanah table is laden with delicacies representing optimism for a sweet future. No sour or bitter dishes have a place on this joyous table - not even, according to some traditions, nuts, because they might have some tartness to them.

Instead, dishes abound with honey, rasinis, sweet carrots and apples - all seasonal reminders of hope for the coming year.

Rosh Hashanah is a time for self-examination and the commencement of the period of repentance before the day of divine judgement which folows on Yom Kippur, Sept. 22. The shofar, a ram's horn whose tradition in Jewish history stems from the time when God permitted Abraham to subsitute a ram for Isaac as a sacrifice, is sounded on Rosh Hashanah. Blowing the ram's horn is a symbol of the complete faith of Abraham.

My father's family, of German-Jewish heritage, has its own symbolic foods for this festival, many of which have been with out ancestral family in Bavaria for centuries. My mother, born in this country, learned these recipes from my German-born grandmother and aunt. Unlike the tables of Eastern European Jews, our meal does not include such favorites as gefilte fish, tzimmes (sweet carrot casserole) or honey cake. Instead, we serve sweet and sour carp, zwetschgenkuchen (plum pie) and apple streusel, and other dishes.

After the traditional Hebrew blessings over candles and wine, our meal commences with the prayer over the two challahs, the sweet bread representing the double portion of manna which the Israelites ate in the wilderness during their flight from Egypt.

After the blessing over the challah is recited, an apple is dipped in honey and a blessing made asking for a sweet and good year. Fish at Rosh Hashanah and on Friday night represents immortality, fertility and the special relationship between the Jewish people and the Torah. Next on the menu comes chicken soup with nockerln, round dumplings made from flour and egg.

In Germany the main course would have been roast goose with cabbag salad, potatoes and carrots. From this first young goose of the season my grandmother would begin saving the schamltz, or fat, for cooking oil until Passover. (Goose fat was especially useful at Hanukkah to fry the potato pancakes.) In this country my family has substituted roast chicken served with seasonal vegetables including, of course carrots. Carrots, too, have their symbolism at Rosh Hashanah. The German mohrruben, as the Yiddish meyrin for carrots means to "increase or multiply."

o authenticate the dishes handed down from Bavaria. I was fortunate to find the well-worn book of favorite bride almost a hundred years ago. They have stood the test of time and I hope that this yeat you, too will enjoy trying some of them.

SWEET AND SOUR CARP 6 servings 1 carp (3 1/2 pounds), pike, trout or haddock Salt 4 cups water or enough to cover fish 1/2 cup wine vinegar 1 lemon, sliced and seeded 1 medium onion, sliced in rings 1 bay leaf 1 teaspoon peppercorns 1/2 cup raisins 1 tablespoon salt 5 whole colves 1/2 cup brown sugar 4 or 5 gingersnaps or lebkuchen

Clean, slice and salt the entire fish. Let stand overnight or several hours. (My grandmother preferred using winter to summer carp for this dish and always included the head as it adds taste to the sauce.)

Boil together the water, vinegar, lemon, onion, bay leaf, peppercorns, raisins, salt and uncovered for 30 minutes. Then add brown sugar and gingersnaps. Gingersnaps add color to the sauce. Simmer 10 to 15 minutes more until the fish is done. It should be firm to the touch and the flesh should leave the bone.

Remove fish from liquid and take meat from the bones. Arrange on a platter.

Boil liquid 15 minutes longer and let cool. Then strain, removing the onions and raisins from the strainer. Pour the liquid over the fish and garnish with the raisins and onion rings. Refrigerate until the sauce jells. Serve as an appetizer the following day.
