There is nothing tastier and more flavorful than a homemade curry sauce. This could be said of all foods, cooking from scratch always results in more delicious products. The only reason why people even take short cuts is out of time constraints, or feelings of laziness (yes, it happens to the best of us). There are plenty of nights where I get home from lab and feel too tired to cook and the best I can manage is to eat some fruit, or make some pasta (or hope for leftovers in the fridge!).
