Show at least one cut open and describe the flavor and juiciness etc.

Location may help as well (city and state or country). There are a fair number of different types of citrus, so you may need to wait to see what it looks like when it starts to ripen. I don’t know anything about growing citrus outdoors, but indoors the ones I have grown may have blossoms, green fruits, and ripe fruits all at once.

I agree - cut two open - one lengthwise and one across, and post photos.

The foliage looks small for a grapefruit .

Tasting something unknown is a bit risky, and probably unnecessary for an ID.

One can sometimes narrow down the citrus variety by looking closely at the leaves and petioles as well as crushing the leaf and trying to detect a certain smell.

For example grapefruit and pomellos have prominent winged petioles; Lemons often have leaves with scalloped margins and crushed leaves smell like lemon -- also, there are no winged petioles and petioles are very short. Limes have leaves with a definite crushed lime smell and taste. Mandarins have petioles with no wings. Probably same with oranges. Some citrus are very thorny like key lime.

When all else fails, you will have to wait until your fruit matures, colors up and ripens to know for sure. Then take a pic. Also cut it open and take a pic. Note if rind peels easily; note the thickness of the rind, how much 'rag', if segments separate easily. Last of all -- taste!

But at this point, it's probably an orange, Clementine, kumquat or mandarin. LOL!

In this instance the plant is clearly a citrus, with as much information as possible being needed to be provided by the original poster in order for anyone here to be able to make useful suggestions. As is often the case with orchard fruits. With what the outside of the fruit looks like - and even what the inside of the fruit looks like - alone often not adequate for this.

I have to agree that suggesting to taste an unknown item, citrus or not, for identification is not really what we should be doing NOR should anyone take that advice from a "someone" out on the web.

I tried out a few different identification and herbal social media groups over the last year+ and I unfollowed every single one except one that I recently joined as too many people swear with absolute certainty a plant is something it is clearly not -- even in the face of botanical resources that made it painfully clear. The ignorance and plain stupidity is amazing. And don't even get me started on stewardship as that broke my heart.

You may be right, in fact, I'm sure you are. But do not get people in the mind to take this kind of advice from the internet. It might not be dangerous here but it certainly is elsewhere.

So if somebody posts asking about an orchard apple or a grape cultivar - on through the list of clearly recognizable edible favorites - you don't think they should find out how it tastes and add that to their description of the fruit also? Just because some other kinds of plants are poisonous?

Original poster made it clear at the start they could already tell it was a citrus, just wants help figuring out which particular citrus it might be.

As a matter of fact it is nothing what OP has said:

" Hi, so I just came across this plant in the garden of the house I recently bought and it has fruit growing on it (not ripe yet). Being a couch potato I don't know which one it is. My initial guess was grape fruit but grape fruits are quiet large at this time of the year as I've seen in other plants. Will appreciate the help. Thanks "

Last I checked, a grapefruit was a citrus........the OP was just astute enough to know that what they had wasn't a grapefruit but they could intuit it was a citrus of some type.

I'm all for tasting it! It's a citrus, how could you resist?

The leaves look like my Satsuma. They are an awesome small citrus tree. Mine would make over 100 fruits.

Could also be a kumquat (Owari), if the fruit has reached its peak size. Or possibly one of the smaller mandarins like 'Pixie'. Leaves look smallish to me. But I think you'll have to wait for fruit to ripen.

I don't think tasting is a good idea until you know for sure what it is. Maybe cut one open and post a picture of the flesh and seeds. Then I'm sure someone here should be able to nail down the species.

What could go wrong if one cuts open the fruit, touches it and brings the finger to the tip of the tongue for a taste?

According to the majority of Debbie Do Nots on here, one would keel over, gasping and wheezing, before suffering a violent and agonizing death, but a few of us with more faith know better!

i think you scared OP away ... lol ... never did get pix of the interior of the fruit ...

You who? This forum is not for the faint hearted. We roll the way we roll.

Hey guys, sorry I disappeared I did open this forum a few days back but was too tired to actually right anything. Sorry I didn't take any pictures but when I cut open the fruit I could instantly tell from its smell it was citrus limetta aka mosambi. I did take a gamble and tasted it as well and it just supported my initial guess. Thanks for taking interest guys!
