Yes you can make them ripe faster using olive oil but you can't make them taste just as good,if you do.
This is done if you intend someone else to eat the figs(as when you sell them to a restaurant).
Best Bet is to reaserch and find early cultivars.
For you Jon,and other hot dry climate I advice Florea, fig,and you will be 3 weeks ahead,in getting,main crop figs, ripe,without any oilling.
And even better let's find a fig early like Florea and tasty,like,Madeira Black.
This should be our goal.
Out of over 200 common cultivars,in existence,,I have no doubt there are many more early cultivars waiting to be discovered.
