Yes you can. I do not know if this works all the time but for the past few weeks I have been buying strawberries at Aldie's for $1 and there are always 2 to 4 that are not ripe. Take the ones that are unripe and place them on a piece of aluminum foil on top of your kitchen counter. In 6 to 8 hours rotate the strawberries so the other side is exposed. You will noticed that the side that was down will be red. Let the other side down for the same time and you should have an all red strawberry. Cool them down in the fridge are whatever you were planing to do with them. Good luck, I hope this is not just a fluke and works with all strawberries.
