Aah....you don't defrost these, you cook from frozen.
I often take things that say 'cook from frozen' and let them defrost, the whole or just in part, and then fiddle with them. It can make the difference between something being 'meh' and something being yummy.
OC you have to not let them 'linger' once they are defrosted but ...
For instance there are a couple of Lidl frozen vegetarian 'cook from frozen' meals which I very much like. The tagliatelli arabiata is YUM but I like to add big dollops of herby cream cheese and some harissa to it; I do this when it is defrosted and then warm it gently in the microwave, or on the hob, stirring often, before giving it a really good blast to get it piping hot throughout.
With a curry, I'll sometimes hoik out the frozen lump of rice to keep in the freezer, and prepare a spiced caramelised onion-and-spices as described above, or some thick tomato and chilli/garam masala, then stir that into the beginning-to-defrost main curry bit until all is well blended. Then cook frozen lump of rice as seems most appropriate while gently simmering the main curry bit on the hob or also in the m/wave.
The instructions are not orders to be obeyed at all costs, just a set simple process which anyone , no matter how (in) competent or (un)knowledgable they might be, can follow and which will result in an edible meal.
