I could make Japanese curry every day honestly. You can get the curry blocks at a lot of grocery stores’ Asian aisles (if you’re in the US) or order on Amazon. They look like this:

The recipe is dead simple. The instructions on the box are 99% of the following, so just use that. Half a box makes about a 2-3 full servings and a full box makes 4-6.

1. Make rice or noodles (I put white rice in a rice cooker). Do the rest while it cooks.
2. Chop about 3-4 potatoes into 1-inch cubes.
3. Add whatever vegetables you want. (My version: Chop onion into 1-inch slices, chop carrots into tiny rounds, and optionally dice a little bit of red apple)
4. If you eat meat: brown meat in pot with a bit of oil (I like pork the best but use anything). Then toss in veg and fruit to cook a minute or two.
5. Toss in your potatoes and cover with water (2.5 cups if half a box and 5 if full box).
6. Bring to a boil and then reduce to simmer. Simmer until potatoes are done (10-ish minutes depending on potato size)
7. Toss in curry blocks and stir until all dissolved and thickened. I also throw in a tiny splash of soy sauce here sometimes.
8. Eat with rice or noodles.

You can improvise or change literally everything here if you want, too. I can probably make this in my sleep at this point lol

A quick Google search says that the curry blocks are vegan, so it’s easy to adapt. Found this recipe for it (pretty much the same as mine): https://sarahsvegankitchen.com/recipes/vegan-japanese-curry/
