OK, here are my tasting notes :
A) Solar's Place
Not particularly good as an accompaniment to a main course, but absolutely superb as a stuffing for paratha, comparable to Masala Dosa at its best.
B) 976BAR
1) 2" cubes of potato are very large
2) 2" of ginger is rather vague : I buy very large ginger, and if I were to cut a 2" piece out of the middle, it would be enormous ! Weights are probably more useful in a group test recipe.
3) "add the spices and fry for about 30 seconds" : the question is, "which are the spices" ? As there is no mention of introducing the ginger and garlic anywhere else, I assumed these were included, but I also included the garam masala, not seeing that this was to be added much later in the proceedings. Perhaps better to be more specific about exactly what to fry for about 30 seconds.
4) Mustard seeds : I have black, brown and yellow -- not at all clear which were intended.
5) Salt : there is no mention of salt anywhere in the recipe, as a result of which I am afraid that I found the end result completely tasteless; perhaps it should say "salt, to taste", with a suggested quantity.
Adding salt made a significant improvement, but adding spinach, red pak choi & mizuna leaves led to a superb Aloo Sag. The strength of this dish is the mustard seeds.
C) Balti cookbook
Excessively hot, and needing six potatoes, has resulted in excessive waste. Also too tomato-ey. No salt, so no flavour.
D) Dipuraja
Suspect I may have used curry leaves rather than methi leaves (jar unlabelled), and dish failed to impress (tasted like Charlotte potatoes rather than Bombay Aloo, until coriander leaf added whereupon whole thing livened up). Unlike SP's, not so good by itself, but the best so far as an accompaniment to main course. Recipe leaves almost everything to the imagination, so no idea whether I re-created his dish accurately. Mildly salted, but could have used more.
E) ChewyTikka
Quantity of potatoes unspecified. No salt. Recipe failed to convince; it was satisfactory, but failed to impress. Le Khanh & I agreed that, of the five tasted/tested so far, this one regrettably comes last. There was nothing wrong with it per se, simply lacked character.
F) Undercover Curry
Nicely salted, but surprising lack of any tomato (pur
