Figs only ripen on the tree, not in the fruit bowl or anywhere else, so it's really important not to pick them until they are thoroughly ripe. In the UK ripening will vary, sometime between August and the end of September. When figs are growing the stem is rigid and holds the fig often perpendicular to the branch, so a first sign of ripening is when the figs are hanging down upright. The next sign to look out for is colour. They should be a maroon red colour with a yellowy green stem. The figs are ripe when the flesh yields when pressed. There may also be a crust of sugar at the base and the formation of cracks in the skin. When they are ripe they will only keep for about 10 days, so if you have bought them, plan on using them as soon as possible. The best way to store them is upright on kitchen paper. Depending on their size you could use an egg carton or a tray.
