Uncompromising is an adjective, so it needs a noun like dedication or standards to accompany it. In this case you'd have to add "to" because you are dedicated TO something. You could also phrase it as: "The teacher's uncompromising standards FOR a particular ingrediant of curry, potatoes". Instead of particular, you could use "a specific", "a special", or "an important" here I feel this helps the sentence flow better by putting emphasis on the single ingrediant
