When choosing fruits at the market, one should always ensure that there are no blemishes or bumps. If they have been banged or dropped the bruise will start a rapid chain of events that will ensure the fruit ripens extremely quickly. Fruit is also made up of a large percentage of water, so you should pick fruit up in your hands. The fruit should feel quite heavy signifying the amount of water inside, heavy apples for example will be full of juice and crunchy to the bite. If they are light they will have less juice inside and will taste foamy when bitten.
