Indians pickle just about any vegetable, fruit, berry and nut. Pickles are intended to pack strong flavors in small quantities, so they are never consumed by spoonfuls. They are meant to enhance breads, rice and other mellow-flavored items during a meal. The majority of pickles are spicy hot, containing a high proportion of ground red pepper (cayenne). Others are milder, but all pickles are laced with spices. The lemons found in India are much smaller and juicier than their American cousins. At times, your local Indian grocery store might stock this variety, so buy them in a hurry before they disappear. The usual kind available in your supermarket will work just fine, too.
