Okra (Hibiscus esculenta)

Okra (Hibiscus esculenta) is a member of the mallow family, Malvaceae, and may be the only member of the family to be used as a vegetable. Okra is a popular ingredient in Creole and Cajun food. Okra pods contain a gummy substance that thickens any dish to which they are added. Prolonged cooking only promotes this gumminess, so minimal cooking is best.

tomato (Lycopersicon esculentum)

The tomato (Lycopersicon esculentum) is a member of the nightshade family and is composed of more than 93 percent water. Lycopene is the pigment responsible for the red color of tomatoes and has demonstrated antioxidant activity associated with a lowered risk of cancer.
ABC plants only organically-grown heritage tomatoes. “Schimmeig Striped Hollow” is the variety shown here. It is not as high in lycopene as the redder varieties, but it is great for stuffing as it really is hollow.

The sweet cultivars, like this ‘Gypsy’ hybrid, are used to add flavor to cooked dishes as well as salads, relishes, and chutneys.
