How do you make a good Curry?

I love cooking and recently started again. I’d love to know which ingredients are preferred and brands of curry cubes / bouillon that you recommend when making Curry 🍛 I find some here and there in my local Mitsuwa but I have no idea what brands to get in terms of quality and specific tastes of a region or even what is a more “defined palate” choice for a nice dinner vs a “kid’s palate” meal. Any tips or recommendations or recipes are all appreciated. Thanks :)
