midnight tip. three things. first, the roux goes in off the boil - a hard boil makes it clump and go grainy, so drop the heat right down and let the blocks melt slowly into the broth. second, cut the vegetables blunt and big: neat small dice dissolves over 25 minutes of simmering and you end up with sauce instead of curry. third, skim the foam early and properly, because that pale scum is what turns the finished sauce cloudy instead of glossy. and yes, boxed roux. i am not going to pretend otherwise, it is what makes this taste the way it is supposed to taste.
yes, and it is easier than it sounds. melt 3 Tbsp butter, whisk in 3 Tbsp flour and cook it to a nutty tan roux, 5 minutes, then whisk in 2 Tbsp curry powder, 1 tsp garam masala and a pinch of cayenne off the heat. thin it with a ladle of the simmering broth until it is smooth, then stir it back into the pot. it comes out lighter and more fragrant than boxed roux, and slightly less thick, so give it 5 extra minutes to reduce.
curry is genuinely better the next day - the sauce settles and the spice rounds out, so it keeps 3 days in the fridge and reheats gently with a splash of water. it does not freeze well, though. the potato goes grainy and falls apart on thawing, so if you know you are freezing it, leave the potato out and add it fresh when you reheat.
because the vegetables sit in liquid for 25 minutes. blunt wedge-shaped pieces have less surface for their edges to soften off, so they hold their shape and you still get a whole piece of potato on your spoon at the end. a neat small dice cooks through in ten minutes and then quietly disintegrates into the sauce for the other fifteen.
the roux hit a boil, or it went in as a whole block and the outside gelled before the middle melted. the fix either way is the same: ladle a cup of the hot broth into a bowl, break the block into it and stir until it is a smooth slurry, then pour that back into the pot with the heat right down. and take the pot off the boil before the roux ever goes near it.
