Firstly: I did not leave out potatoes. I just cook them separately. I enjoy the little yellow potatoes, that are indigenious to northwestern Spain´s Galicia Province, which were brought to Spain in the early 1500s from Perú and are called Cachuelos here. They have very creamy yellow interiors. I prefer not to blend this flavour with cabbage or cornbeef so I cook all separately as I had been taught.
The next answer: Yes, you can leave out the orange with the cloves, and you carrot, black pepper and onion as in the other posted recipe on this thread.
3 Pots: I prefer to separate the 3 main ingredients, the cornbeef, the potatoes and the cabbage. This is how I have learnt to make it from some Irish friends. Since there are only two of us ( the grown gals are married ) and I have a dish washer, this is not a problem.
The aromas of Cabbage: It is not the most pleasant of aromas, and for this reason, I mentioned it.
Hope this answers all.
