Curry powder is a blend of spices. Curry spice blends include turmeric, cumin, coriander, mustard seed and chilies. Epazote makes bean-eating more socially acceptable. Florence fennel, the other type, is a celerylike plant with leathery foliage and a bulbous base that's eaten as a vegetable, sauteed or raw in salads. Horseradish and wasabi.
Fresh horseradish is a gnarly-looking root.
Grate its milky interior for a hot 'n' spicy garnish. Once the root is cooked, the heat goes away. Lemon grass is not to be eaten. It gives a lemony tartness to foods. Look for tight, firm leaves.
