What the hell kind of curry are you making? Good, Nipponese curry is just
>chicken
>chicken stock
>onions
>garlic
>ginger
>potato
>carrot
>curry roux
<butter
<flour
<garam masala
<curry powder
<pepper powder for spice
Which is 8 ingredients, and not all recipes use garlic and ginger. You can easily make a proper Nipponese curry with just a slow cooker and a pan.
>caramelize a lot of onions
>throw it in slow cooker
>saute garlic and ginger and throw that in too
>throw in chopped vegetables and chicken
>make basic chicken soup (I seriously hope you can do this)
>mix roux in when the soup is almost ready
>serve on rice
Making roux yourself is mildly complicated.
>melt better
>add flour
>keep stiring
>add spices
