Bacon is made from the meat of a pig. It is cured and smoked, and then sliced into thin strips. The part of the pig the bacon is taken from depends on what part of the world the bacon is made in. In America, the belly is used, and in Australia and the UK the back is used.
Bacon is most often eaten with eggs for breakfast.
Basil is a herb that is often used in Italian or Thai food. Sweet basil is used in Italian food and Thai basil is used in Asian food. Basil has a sweet, strong smell.
Basil likes to grow in hot, dry conditions and does not tolerate frost at all. Basil stops producing the oil that gives it its flavour once it starts to flower, so you should pick off the flowers as they develop. You can leave one or two stems to flower without affecting the rest of the plant, so you have some seeds for next year.
Bay leaves are dried leaves from the bay laurel tree. Bay leaves are used to flavour soups and stews. The flavour of the leaves gets stronger when they are dried.
The bay laurel itself can grow into a large tree, but is usually kept in a container and clipped into shapes by topiary. Bay trees like a frost-free area.
The bean is the seed of the bean plant. It is eaten for food, with or without its pod, or grown to improve soil in a garden or farm. Beans are in the same family as peas. The picture is of some different coloured string beans, still in their pods.
