CHICKENS PURCHASED from the chicken lady . . . coconuts opened by the grower . . . tomatoes layered into a mountain of freshness. All items brightly displayed for inspection, purchase and praise. These are the foodstuffs of Africa's markets that photographer-painter Sherrie Dorr Bork recorded on film, interpreted in acrylics and recently recaptured in Washington one weekend.

As an artist, Bork's primary interest during two years in Nairobi, Kenya's capital city, was in photographing the markets and the people and then transforming the works into large-scale acrylic paintings. Occasionally, her shopping found her traveling directly to the Kikuyu tribe, the agrarian growers of the city's produce.

She traveled to Lamu, an island with few 20th-century comforts, to learn about the Swahili peoples. Cooking became a logical accompaniment to her painting and photography, and that led her to two island teachers. First, there was Famau, a cook in a 17th-century resort house who introduced her to two dishes that are now standards for all her African parties: smaki wa mchuzi and kuku wa mchuzi.

Then Amina, known as Lamu's best cook, shared her small, stapled recipe book and explained the key spices and seasonings of the Swahili culture, a mix of Arabian and African roots. Hummus, a popular appetizer commonly recognized as a Middle Eastern dish, is a typical Swahili blend of two cultures, though appetizers play a secondary role to entrees in African meals.

The final influence came from the American owner of a restaurant and gallery in Nairobi; the nightly buffets inspired Bork's cooking, and the environment influenced the decorating of her present Southeast Washington town house with wicker, straw and ceramics.

Bork's Sunday night Swahili supper for 45 guests, some of them friends from Kenyan days, began Sunday at Eastern Market and Maine Avenue. "The coconuts are the biggest in the city at the waterfront site," she explained.The day was then spent cooking.

Between preparation and presentation, the cook returned to her role as artist, completing work on her two seperate one-woman shows: American market paintings at the Gallerie Triangle in Southwest Washington and photographs of the people of Maasai, Kenya's most famous tribe, at Volta Place Gallery in Georgetown.

The dinner menu included dishes from other African and South African ports, but it centered around coconuts, rice and nuts, combined with fish, chicken, beef or lamb. Her African recipes use large quantites of garlic, onions and lemons and the mchuzi spices: cumin, cardamon, coriander and curry. Turmeric, ginger and cinnamon play a lesser role, but the overall theme is freshness: coconuts freshly opened, peanuts freshly shelled and seasonings freshly chopped.

The small galley kitchen, equipped with few modern appliances, was in African re-enactment, for the chopping, pounding and grating gave the room an old-fashioned village atmosphere. As Bork sampled, she added more garlic or onion to match the spiced rememberances from Famau or Amina. Baskets came down from the walls; straw trays appeared under hand-fired Kenyan pots. It was time for an African feast.
