They will ripen on the plant-leave them to do what they need to do-they will taste better for it
In any case a sunny windowsill is not the best place-at the end of the season in a drawer is ideal-they need warmth more that sun to ripen.
It is also a good time to pinch out the tops of the plant-it is getting quite late in the season to expect more fruit to form, grow and ripen.
Leave the plant to concentrate on getting the ones on it now to ripen.
