I love mushrooms and have no reason to dislike 'Maderia' even when it is spelled incorrectly. However, I'm afraid I found these kievs remarkably disappointing, especially considering that they are part of the 'Finest' range and are not cheap. The chicken was dry and stringy and I could hardly taste the mushroom flavour at all. An experience I will not be repeating.
I tried these as a change from the usual garlic butter Kievs and I found them quite tasty. As a bonus the filling stayed inside until I cut them open rather than leaking out in the oven.
Doesn't really work well.
Bit of an odd flavour combination that doesn't really work. Didn't smell nice when cooked either.
