Are limes kosher?

Shalom, Thank you for your question. If you are referring to the raw citrus fruit, “lime”, then the answer is yes, it is kosher. All fruits, vegetables, and grains are kosher. Perhaps your question is based on the fact that perhaps the lime fruit was grown by a process of grafting. Are grafted fruit permitted to be eaten according to Jewish law? The answer is yes, even if the grafting itself was prohibited, the resultant fruit is permitted. (As an aside, it is not clear to me that the lime fruit is in fact grafted in a forbidden manner). An additional law that related to fruit is the law of Orlah – that fruit is forbidden for the first three years after planting. Unless you know for certain that your lime comes from such a tree, one does not have to worry that perhaps there is a chance that it is an Orlah fruit. The law is that outside of the land of Israel, all doubtful fruit is considered as not being Orlah. And inside Israel (where the laws of Orlah are more stringent – none the less…), one may follow the ruling that the majority of fruit does not come from forbidden plants, and therefor the particular fruit you have is assumed to come from the majority – and is permitted. Another issue that may arise in eating a lime is if it is grown in the land of Israel. Then the laws of tithing, and the laws of the shmittah, sabbatical year, need to be taken into consideration. Bottom line – or “bottom lime” – you may enjoy your fruit. Blessings.
