Hello, I’ve had both of these boxes and they do mean one entire box (I’m surprised there are so many comments and no one is answering your question).
My recommendation is to halve the amount of liquid and meat, while keeping the vegetable amounts the same, and use half a box of curry roux (note: I always use a whole carrot, I’ve never use half). One box includes two packets with 4 vaccuum sealed cubes in each, so half a box is much easier to make than a quarter.
The flavor is the same, and it’s great. I’ve tried it and can confirm that if you use any less it’ll be a bit too watery. Likewise, if you use less than half then that means any leftovers will no longer be sealed (unless you use scissors while peeling off the plastic to preserve the seal on half a packet)
Here’s a source where you can double check the recipe.
Also, trust me when I say it isn’t too much. It produces a crazy amount of curry. Half a box is enough for one dinner, plus two servings of leftovers, for a single guy like myself. A full box is basically designed to feed a family.
