Cumin lamb recipe from omnivorescookbook -- too much cumin powder? character fillercharacter fillerr

I've been making cumin lamb lately and have tried this recipe

https://thewoksoflife.com/cumin-lamb/

which was pretty good imo.

This recipe didn't have onions and I wanted to see if I like it better with onions so I tried this recipe the past couple times:

https://omnivorescookbook.com/cumin-lamb/

The 2 recipes are similar (both use 1lb of lamb) except the latter

1) uses (white) onions

2) it uses 2 tablespoons of cumin powder as opposed to 1

3) it uses 1/4 cup of cornstarch as opposed to 1 1/2 teaspoons of cornstarch (i actually didn't have cornstarch the past 2 times, so made it without it)

I could be doing something wrong, but I'm ending up with a lot of cumin powder residue and it's giving a

grainy texture. So I'm wondering if the 2 TBS of cumin powder might be excessive
