Niku-Jaga

Today I tried to make Niku-Jaga, a Japanese traditional and domestic dish.
To tell the truth, it did not seem like Niku-Jaga.
I think No Japanese will call my dish Niku-Jaga. It is difficult to get Japanese food materials in London.
For example, carrots in UK had a strong scent compared to Japanese ones and we can not get slice cut beefs proper for Niku-Jaga.
But I could say it was Niku-Jaga confidently because my friends in London are not able to tell whether it was Niku-Jagaor not.
